how resource heavy and slow for what it is, how notifications break a lot of the time, how obtuse and unintuitive it usually is to do some simple stuff like sharing meetings and how everything thats not an absolute core feature will glitch out 8 times out of 10.
i’m sure some of these were fixed while they broke other stuff, they fuck around with it all the time. im thankfully not being forced to use it for a while right now.
