On some production devices our application fails to find the keychain item associated with our application where we store our JWT tokens. We have been unable to reproduce this in house for many months. Today I restored a phone from a backup using the device to device transfer of data as I replaced my personal phone. On that device now when opened each time I am prompted to login again and it appears my token is never saved to the keychain. Upon every successive reopen of the application I see this error in the console. Error fetching keychain item - Error Domain=NSOSStatusErrorDomain Code=-25300 "no matching items found" UserInfo={numberOfErrorsDeep=0, NSDescription=no matching items found} I currently do not see any errors in the console related to the saving of said token. We access this token with the after first unlock security and we do not allow iCloud backup for these tokens. Any help here would be appreciated. I'm not sure what would cause an issue like this. Other applications on my device do not seem to have this issue, so Its likely something we're doing code wise that may be different. Any hints as to what to look for here may be of help. The previous device or any device i have not created from a backup works as intended, including about 95% of our production users.
