Okay, I didn't see where to submit a complaint, but I did get information that unlocked phones like ours have to undergo rigorous testing before updates, that they have to be sure ALL carriers can support it before they roll it out. So, if I am not mistaken, Verizon is the only carrier so far in the USA that supports Android 11. It might be up to all of the carriers to get updated before we can get it. ☹
Okay, I found another tracker, and it, indeed, says that, out of the four big cell service providers, Verizon is the only one that released it for the A50, and Sprint has it under testing. There is no word on T-Mobile's and AT&T's progress for the A50.
