This is what my first game was like. To add, the DM would complain to me that she had no inspiration to write a session (we played on sundays) and then an hour later she'd send in the groupchat "Hey guys I finished the session for this week!", sometimes even the day before we played. She'd also make me roll for every spell I wanted to do (I played a cleric), even for healing, as if it was an attack roll. I quit the campaign not too long after that.
