Since the Feb 2020, it won't open at all. I can only access Gmail on Chrome browser. Which afterwards I close the tab and clear history, I shouldn't have to do all that if the app is installed AND working properly. Not sure what's going on, but 2022 updates are causing more problems, than improvements on keyboard, Gmail, and YouTube. With fingers crossed, I'm going to uninstall them, then reinstall to see if that helps. Wish me luck!
