Frequently have multiple tabs leave their groups, ruining all organisation I have done. Tabs will then begin to glitch, not moving correctly when I try to put them back into their groups or try to move them through groups to organise them. Closing Chrome causes the tabs to fix themselves and show their true positions, but it quickly glitches again if I try to move them. Restarting the phone doesn't help. Very disappointing and difficult to work with. I would expect better from Google.
