I bought a new phone and I cannot use the code provided by 2FA app on my new phone to log-in.
Before that, I reset my old phone and now I cannot use the code provided by 2FA app on my old phone either.
My one-time scratch codes don't work somehow.
I'm using the computer at home, the only device that "stay logged in" to post this task.
Please give me advice and help.
Thank you and regards,
