The ProtonMail mobile app on Android isn't very good. Swiping emails to archive is very slow and often messes up. Sometimes after archiving an email, it randomly reappears in the list until I manually refresh again. Just a lot of little annoyances such as these has turned me off from ProtonMail. Also, if you want to have Calendar integration, there is none in ProtonMail.
