My banking app still hasn't been updated (small bank), and a few other "developer-type" and other specialty apps haven't, as of Beta 2, so I went back to Pie (which gave Google some good troubleshooting - no more automatic replacement because the phone is in the bootloader, won't get out of it, and the PC doesn't recognize that there's anything plugged into it). I'll wait until release - I'm comfortable with Pie, and really don't need any of the Q changes or additions. (As for gestures, Nova does everything I need. The launcher was one of the first things I replaced on the phone.)
