So I took my pro1 and pro x and switched Sim cards.. This confirmed that, in fact, my Pro 1 is unable to do calls anymore. There was no problem with either sim card in my Pro1x. So, it may be that my good battery performance on the Pro1 is due to the fact that it can't use a SIM. I sort of don't care enough to do anything about it as I do not ever use my Pro1 as a phone. (I rarely use my Pro1x as a phone and it works).
This also suggests that, to the degree that it is a LOS 22 problem, it does NOT seem to be a problem with the Pro1x version of LOS 22.
Round and round we go... 😉
