problems:
1 - the reminder doesn't work in the list that is shared among the group. it works only for me
2 - There is no comment section in each task. There is only notes section where everyone can add something but also everyone in the list can edit it which is not a good thing of course. Also it does not mention who added the note and what date or there is no notification when someone adds something in it. So i have everytime to write my name and date.
3 - And there are no NOTIFICATIONS if someone noted something or changed something in any section of the task.
