I installed Boxcryptor 3.08 on my iPhone running iOS 14.6 and synced it with my Google account. I then opened the iOS "Files" app and opened the Boxcrytor folder, opened Google Drive and then I renamed "My Drive" to "Blabla Google Drive". This gave an error in the Files app, but it still did show the folder under its renamed name (tagged with 'error'). I then long tapped the renamed folder "Blabla Google Drive" (again, with the 'error' tag) and added it to my Favorites in the Files app on iOS.
Now, when I try to remove the "Blabla Google Drive" folder from my Favorites in the iOS Files app, it keeps on reappearing. Exactly the same as described here: https://discussions.apple.com/thread/250229589.
So I'm unable to remove it from Favorites.
In addition, when I now try to add this Google account to my Boxcryptor app on MacOs (v2.41 on Big Sur), Boxcryptor no longer auto-recognizes my Google Drive on this account when I mount it. When I mount another Google account, it correctly auto-detects it.
I've tried restarting my iPhone, Mac - removing and reinstalling Boxcryptor on both and I tried repeating the steps and actively deleting the Favorites entry (also adding another Favorites entry with the same name and then deleting it) and nothing seems to fix it.
Needless to say it went wrong when I renamed the My Drive folder, but any idea how to fix this? Might also be an idea to see whether this My Drive folder could be configured as read-only, as is the main Google Drive folder already.
