I'm having the same problems, Gmail keeps crashing and Facebook links crash that too, terrible release !
Yes, I have the same issues.
Outlook - not working at all.
Gmail - keeps receiving notifications that the app doesn't work properly (in the Device care)
Facebook - links doesn't work, but when I changed it so all links are opened in external browser (Chrome) it works.
I also had issues with Duplicate WhatsApp (had to uninstall and reinstall) and with Smartthings.
