Check if other codes from this app/device work and check if other device would show you a different code. My old laptop now has its time a few minutes off so my TOTPs from KeePassXC don't work anymore.
And, most important thing you didn't mention, did 2FA ever work for this account? Did it suddenly stop working?
Apple violates your privacy regardless of what keyboard you use
Google. Use Searxng for search, Firefox/Librewolf for browser, Newpipe for Youtube, Graphene instead of default Android, literally anything for calendar and notes, and FDroid for apps. Don't let Google's services destroy your privacy.
Paranormal things don't exist. Every such story always has zero proof or has a much simpler explanation that doesn't involve ghosts and magic.
I use KeePassXC for TOTP on computer and Aegis on Android, but I didn't check if Aegis can change to sha256 like KeePassXC can.
Edited: I just checked and found the option for sha256 in Aegis, so 2FA must work with code generated by this app.
