I've been using this for a day, and there are some problems I'm having that I haven't seen mentioned in the thread as of yet.
1. The camera only works with Google Camera. No other app can use it (I either get a black feed or a "Cannot use the camera." message).
2. If I switch to video mode in Google Camera, the app crashes.
3. If I enter any submenu in Gboard settings, it crashes.
4. In the Quick Settings editor, if I pull a setting upwards 8 rows, it returns to its original location, making it impossible to add any tiles from the 8th row and under.
5. Multi-Window doesn't start if I hold the Recents button, and I can't find a setting for it either.
