Are you referring to the google backups not working or the crash I'm seeing with my work sandbox? In either case, I haven't solved either yet.
Regarding the google backups, I'm currently investigating various 3rd party backup options (though it would be nice if the build in Google Drive backups were working).
As for the crash issue, it only seems to pop up a few times then stops, so it hasn't bothered me too much yet. In fact, I've just been looking for a way to disable the Xiaomi crash reporter popups because functionality-wise, I have no issues with the work apps I use (Gmail and Calendar), so the only annoying thing are the occasional popups.
However, since I posted yesterday, I noticed one more bug. Playing full screen videos in Chrome seems to be somewhat broken (at least while watching videos in incognito mode from a certain videos site starting with the letter x lol). It works in the sense that I can tap the full screen button on a streaming video and it goes full screen, but then half the time it renders in the content of one of my other tabs in the left half of the screen and the time scrubber doesn't work (doesn't respond to touches, can't drag it), so I can't skip through the videos.
