Welcome to the fold.

Been running nextcloud for 8+ years. Love the auto upload and bookmark sharing apps.

The contacts and calendar apps support DAV…I use DAVx on android to sync contacts and calendar to nextcloud …haven’t sync’d to Google. Grab it from FDroid. I have an article on my web blob explaining how to do it.

Remember to backup your cloud data and secure your web portal or run over private vpn.

Oh and go find the php updater script…it’s a life saver.
