kzintiwife’s suggestion solved it for me. Just remember to get your username and password ready before you delete (or from another device like a PC) first, otherwise you’ll have to start from scratch.
“i found i had to uninstall, clear cache, reboot, then reinstall. that seems to have fixed my android problems. and it had to be done in that order… any other didn’t seem to work… so just doing cache, just doing reboot, just doing uninstall.”
