Before troubleshooting, check the official ChatGPT listing in the App Store or Google Play for the latest device and software requirements.
If you're looking for an older conversation, see: Finding your chats, projects, and files in ChatGPT. A chat missing from the sidebar hasn't necessarily been deleted.
App crashes or freezes
If the app crashes or stops responding:
Close and reopen ChatGPT, then try the action again.
Check the OpenAI status page for an incident affecting ChatGPT.
Install any available ChatGPT update from your app store.
Check that your device's operating system is up to date.
Try a different connection, such as switching between Wi-Fi and mobile data.
Try the same account at ChatGPT on the web, and note whether the problem happens there too.
If the problem continues, uninstall ChatGPT and download it again from the official app store. Sign in to the same ChatGPT account and try the affected feature again.
Reinstalling doesn't reset usage limits, change workspace permissions, or remove account restrictions. Follow any limit or access notice shown in ChatGPT.
Login issues
Try signing in to the same account on the web. If that works but sign-in still fails in the app, try removing and reinstalling the app, then use your original sign-in method to help identify the correct account.
For browser, cookie, authentication-method, and Android sign-in checks, see: Troubleshooting ChatGPT sign-in.
Device-check errors
You may see an error that asks you to check your device's date and time or internet connection. The message may include DeviceCheckError.
Check that your device's date, time, and time zone are correct. Use automatic date and time if available.
Check your internet connection, then close and reopen ChatGPT.
Install available updates to ChatGPT and your device's operating system.
Try signing in through your browser or using another device.
If your device has been rooted or jailbroken, try a device with an unmodified operating system. Include the full error message when contacting Support.
If the issue continues
See: Contacting OpenAI Support.
Include:
Your ChatGPT account email address.
Your device model, operating system version, and ChatGPT app version.
What happened, the date and time, and the steps to reproduce it.
The full error message and any request ID, or a screenshot that shows them.
Whether the issue happens on Wi-Fi, mobile data, or both, and whether it also happens on the web or another device.
For sign-in issues, when you were last able to sign in, if applicable.
