On new, unrooted, Moto XT2113-2 with Android 11.
1. I have tried BOTH with and without new API.
2. I have ensured that the variable is monitored with a state profile %CELLSRV !~ service.
I have tested calling, texting, and mobile data and all of these are working. And I note that the Mobile Network state profile appears to be working. So it is NOT just that the cell radio/system is messed-up.
I can see there is plenty of past history of discussion about this. But it is working on my rooted, LG V40 with Android 9.
Any suggestions?
