What to do if…
your public transport pass in an app suddenly shows as invalid even though you paid

Short answer

Pause and stabilise: don’t delete the app or start buying duplicate tickets yet. Get your proof of purchase visible (email/receipt/bank line), try the quickest “make it display” fixes, and if you’re challenged, calmly ask for the staff member’s process and any appeal paperwork.

Do not do these things

  • Don’t delete/reinstall the app or “clear storage” in a panic (it can remove locally stored tickets or log you out).
  • Don’t rely on screenshots, confirmation emails, or bank transactions as your “ticket” at inspection—many operators won’t accept them, and even where a screenshot might scan, it may still be treated as invalid. Focus on getting the live ticket/pass to display in the required way (app/PDF/Wallet).
  • Don’t argue or raise your voice with drivers/inspectors—focus on getting the issue recorded and what you need to do next.
  • Don’t ignore any notice you’re handed (e.g., Penalty Fare / Unpaid Fare Notice) or miss the deadline printed on it.

What to do now

  1. Move to a calmer spot and make your phone usable (30–60 seconds).

    • Turn off battery saver temporarily, increase screen brightness, and disable VPN if you use one.
    • Set Date & Time to automatic (some mobile-ticket systems rely on correct device time).
    • If you have a portable charger, connect it now.

  2. Collect “proof you paid” that you can show immediately (even if it may not count as a ticket).

    • Open the purchase confirmation email/receipt (from the retailer/operator).
    • Open your banking/app wallet and find the matching transaction (amount + date/time).
    • If your app allows it, capture a short screen recording showing the pass as “invalid” plus the order/reference screen.

  3. Do the fastest “get the ticket to display” fixes, in this order.

    • Toggle Airplane mode on/off, then reopen the app.
    • Force-close the app, reopen, and sign in again if prompted.
    • Check for an in-app restore purchases / refresh tickets option.
    • Update the app if there’s an update available, then reopen.

  4. If you’re at gates or boarding right now, choose the least-bad option to avoid escalation.

    • If staff are present: ask them to advise what to do before you go through (e.g., side gate assistance, checking your booking reference, directing you to the correct help channel, or advising whether you should buy a temporary ticket and claim back).
    • If you’re on a rail service and a ticket check happens: say you paid but the app is failing, show the receipt/bank charge, and ask what they’re issuing (if anything) and what evidence you should keep for an appeal.

  5. If you’re issued a Penalty Fare / Unpaid Fare Notice, switch to “paperwork mode.”

    • Check you get a reference/notice (photo it), and note the time, service, origin/destination, and staff ID/name if shown.
    • Follow the notice instructions exactly. On much of the rail network, a Penalty Fare is £100 + the full single fare, reduced to £50 + the fare if paid within 21 days, and appeals are typically time-limited (often 21 days)—your notice is what counts.

  6. If this is Transport for London (Oyster/contactless) and you’re seeing “invalid”/maximum fare issues:

    • After the journey, check your TfL contactless & Oyster account for incomplete journeys/maximum fares.
    • If you were charged incorrectly, follow TfL’s incomplete journey refund process (they may advise waiting for automatic processing first, and there’s a time window to claim).

  7. Report the fault to the right organisation (today if possible).

    • Ticket retailer/app (e.g., train/bus operator app): ask them to confirm the ticket status and provide a written note that you purchased before travel and the app malfunctioned.
    • Operator you travelled with: ask how to submit evidence if you were stopped or charged extra due to app failure.

What can wait

  • You don’t need to decide right now whether to escalate to complaints bodies.
  • You don’t need to “fix your whole phone” (factory reset, new SIM, new device) today.
  • You don’t need to chase a refund immediately if the operator/TfL system says to wait for automatic processing first.

Important reassurance

This happens to a lot of people—apps log you out, time settings drift, barcodes fail to load, or systems glitch. The best damage-control is staying calm, preserving your evidence, and making sure any penalty/notice is handled on time.

Scope note

This is first-steps guidance to stabilise the moment and reduce the risk of extra charges or enforcement action. If you receive formal paperwork about a penalty or prosecution, you may need specialist advice based on the exact document and operator.

Important note

This is general information, not legal advice. Ticket validity rules and enforcement processes vary by operator and ticket type, and decisions can depend on what you can display at the time.
