Logs out too often. Day-old notifications = error.
Version 8.23.1: A bug has been introduced wherein half of the iOS notifications lead to a 'something went wrong' error. The app was fine before. Please revert to previous. Additional Review (a year or two after the above): The above was never fixed. It seems to happen whenever you don't have time to attend to any notification within a certain number of hours (maybe 24 hours?). New problem: Now the app frequently logs you out against your will, but continues to send you notifications as normal, which simply lead to a barrier (log-in) screen. Finally deleted. Sad. Tidio is/was quite good.
