Stuck on One UI 4.0 beta

[gbutcher1]

So I downloaded and installed the One UI 4.0 for my S21 ultra in October 2021. I haven't had an update or security patch since. I am concerned that I'm stuck on this Beta. I can't remove it. I have tried removing it through my PC on Smart Switch however, I getting an error message saying I don't have enough space on my harddrive however, I have gbs worth of space. I have tried withdrawing from the Beta programme on the Samsung Members however, I get a message saying it has ended. Can anyone help with this?

The beta program has finished.

Hey @gbutcher1 

The Beta programme finished quite some time ago, so it's strange that your phone hasn't updated. Have you tried performing a factory reset, to see if this helps? This will wipe all the data from your phone.
