Reverting to an older iOS
Using an iPad Pro 4th gen wifi, iOS 14.4 has rendered an APP that I use for business inoperable. The developer has "received a ticket" to have the problem addressed/fixed, but it is unknown when the issues will be resolved.
Is it possible to erase my iPad, then restore to an older iOS?
If so, how can that be done? I have a saved backup with iOS 14.3, but maybe iOS 13 would be safest to ensure I can continue using this APP until Apple resolves the issue.
Does anyone have experience with reverting to an older iOS?
Thank you!
