Although it is a good alternative to slack/gmeet/jiira/clickup... However since the app is trying to do too much, it seems to not do these things too well. Sometimes you have to refresh to get the latest updates in documents/planner. Notifications don't seem to work at all for the scheduled meeting for me for some reason. Despite these negatives the app itself is good, but doing too much. I guess that was the goal for the app.
