The trick here is to tap the “Restore” button on the Backer view. That will request your subscription/purchase information from the App Store, to fill back in the missing knowledge of your status.
Let me know if that doesn’t work! It can’t be done automatically by apps, because the request usually requires a password / FaceID / TouchID. So it has to be a manual button press to get it done. But it usually works reliably.
Can this window be scrolled downwardly?! I didn’t imagine that…
I wonder control of this type of transition of windows might not be controlled well as expected, at least for the combination of iPhone X - iOS14 updated from iOS12 (see attached screenshots below).
The windows appearing from the bottom do not reach to the top (there are black spaces left):
By the actions of SETTINGS → Project Backer Options, slightly more parts down to choices of duration appear (but still parts of price and parts of Options and Restore do not appear):
I have fallen for the same problem several times. Arc just forgets my subscription and then I have to hunt down where the “Restore subscription” button is.
Still a problem a few weeks ago.
