Been using Yubico Authenticator app for years since PayPal started requiring 2FA. Two weeks ago the first code from the app stopped working and I had to wait for the second key, which worked. As of two days ago the keys stopped working entirely. Today I removed 2FA from the account and tried adding the app again, but PayPal reports the code as bad and won't accept it. I just used Yubico to auth with GitHub so it's not the key itself that is broken. Updated the app to the latest version and tried manually adding via the secret, all to no avail. After contacting customer support setup Google auth app instead, which works fine. Removed that again and tried adding the Yubico again and still failing, no matter how long I wait before trying a code.
