Google Authenticator is generating wrong OTP (2FA), maybe since Update to Android 9

Google Authenticator (and other OTP generators like Microsoft Authenticator, Lastpass Authenticator) are not generating the correct codes on my Xperia XZ1 Compact anymore. Since I have multiple sites with 2FA authentication enabled, this is not really a fun anymore.

I've tracked down this problem to the Xperia XZ1 Compact that I'm currently using because:

it was working before on my XZ1 Compact (maybe before the update to android pie)
It seams not to be a Google Authenticator problem, since other OTP generators I've tried on my device are all generating the same wrong codes.
On other devices, the OTP generators are generating correct codes.
It does not seam to be a problem specific to Android Pie, since the OTP generators on at least one other Android Pie System (XIAOMI MI A1) are generating correct codes

So I think this is either a general problem with the Sony Xperia XZ1 Compact with Android 9/Pie - or specific to my device. Can anybody else in this community verify this?
