That happens if you have connected your Zoom account with Dryfta and then log in to your Zoom.us account using the same email address with which you're connected in Dryfta.
It simply removes those associated meetings if that happens and then you have to reconnect again. This is not a bug and is basically how browser sessions work.
While using the Zoom integration please ensure that you do not sign in to your Zoom.us account in the same browser in which you're logged-in to Dryfta backend.
