One UI 6 _ data/connection issues

[As1mi]

I upgraded my S22 ULTRA to one ui 6 and have had issues with data and connection [I'm with EE and 99 percent no issues, b4 update] Since update at times I've NOT been able to CALL anyone or RECEIVE CALLS. At times no Internet connection, which are needed especially for work purposes.

I reset mobile data, i wiped cache through recovery mode and the issue was persistent.

I ended up using Odin to FLASH one ui 5.1. No issues after doing that. I recommend people not to upgrade until they have an update for one ui6. 

Maybe I'm not the majority but thought id share my exp.

Same. I updated back in December and hasn't really worked since. I just updated to 6.1 today and it didn't fix it. If fact, it seems to be even worse. Toggling airplane mode used to temp fix it but now that doesn't even do it
Not sure what to do now
