I recall reading a report last night... An app lost access to its
keychain items after an iOS 15 upgrade. The workaround was to "Enable
iCloud Keychain".

I don't think that's a good idea, however. You don't want your secrets
leaving your security boundary and moving to Apple's cloud. In fact, I
stopped using Apple devices back around iOS 6 when Apple integrated
the keychain into their cloud services.
