An Invalid Token (or "token invalid") has to do with the time setting on your device.
Tokens allow you to use the Ibotta app by providing the app with expiration dates and times adjusted for your time zone. We want you to be able to see the proper time in the app so that you can shop and redeem appropriately.
If you are receiving an invalid token message, you will have been automatically signed out of the app and will need to adjust your settings. Depending on your device, please go to your device settings and turn on [or for troubleshooting, turn off and then on] "Automatic date and time".
Once you have this adjusted, you will be able to log back into your account and use the Ibotta app.
