Icons reset and stacked
The phone turned unreasonably slow, then after a restart Arrow started the introduction. All pages were reset, and multiple shortcuts are stacked on top of each other in the persistent app shortcut tray. widgets were removed and the wallpaper defaulted back to bing. I have a screen recording of the mess.

A few days after I started using arrow, the apps started stacking on top of each other with additional copies of apps appearing almost every time i turned my tablet on.
