I noticed this with Bitmoji keyboard too, but so far only once and I haven’t seen it again yet. Not that I use Bitmoji all that often, but I wasn’t able to jump to Bitmoji keyboard earlier today but just tried it now and it worked. I’ll have to keep an eye on it and see if it happens again and under what circumstances…3rd party keyboards are completely broken for me in beta 2. If I select one, it jumps back to the Apple English keyboard. Have tried to disable/enable, uninstall/reinstall but can't get them to work. I've tried Gboard, Giphy and GIF Keyboard. Anyone else has this problem?
