As mentioned above. Would someone on the team be able to switch my carrier to Red Pocket Mobile (AT&T mvno)?
As of now the, 'One UI beta features is not available' and I would like to remedy that.
When no one here assisted me I figured I would try this and it did work out. I took the old SIM and put it in the phone and was able to withdraw from the beta and then I use Smart switch and my PC to downgrade back to stable. Worked pretty well.
