I had terrible battery life on Beta 4 and rolled back to P. I enrolled in 5 this morning and I noticed that I no longer am getting LTE, just 4G. Not exactly a huge deal, but is this a known issue?
It's probably a change in the icon, not an issue at all. You could report it at the Q Beta Issue Tracker, but I think that's what it's going to turn out to be. (I had too many apps that I need to run daily that weren't updated to Q, that I left after Beta 2.)
