Updated Plex today on firestick. Won't allow me to sign in using 4-digit code

Server Version#:1.43.0.10492
Player Version#:

Today i updated Plex on my Firestick. It is asking me to link my LG tv to my plex server on my PC. Every time I try the 4-digit code it says user can’t be authenticated. I used it last night before they update today and all was good. Not sure what is preventing it from linking today. I have tried multiple devices to link like my phone and xbox still same issue. Any advice would be appreciated

I’m hitting the exact same isssue, incredibly frustrating.
My server is up but I can’t log in so can’t use it.

Have tried changing my password and logged out on another device to confirm it’s not a problem with my new device.

I think they didn’t actually fix the outage they had yesterday which was logged on https://status.plex.tv/

I’ve managed to log in now. So the issue might be resolved.
