I recently paid for the subscription to the service but I found a bug in my instance with the Daily tasks.
The same 3 daily tasks from the very first day that I started using Bitrix keep appearing every day even after finishing them and them being crossed out. I can not delete them, nor can I add new tasks to the daily plan. When I add something, it appears for half a second, and then immediately disappears.
I see that you have also reportd this to the Helpdesk - we'll change your ticket support level from free plan to paid as you've bought the subscription - the support team have reported this problem to our devs & will try to assist asap. Thank you!
