Android 12 update

Anyone got any issues with Samsung Galaxy S21 Ultra 5G after Android 12 update where it drops the mobile connections for single and dual sim?

Yes I have this issue on EE.
Just had a Engineer look at the phone run some diagnostics and was told phone is fine you need to upgrade sim card to 5g.
Really !!!!!!!!
Wel the sim card works perfectly fine in my S10+ and was working in the S21U until the OneUI 4 update.
So moderators what shall I do now stop using the phone and put it in the draw?
This is not acceptable on any level!!

Yep I have the same issue, network drops and cycles between no signal and signal but can't do anything. Seems to happen when going to a new area whilst driving / jogging.
