Tasks bugging

I haven't been able to complete any of the weekly tasks within the last 4 days because it hasn't been registering when I'm doing the things required and today it's doing the same with my daily tasks. Only registered half and then stopped working, got to 22,892 out of 50,000 then stopped, 4 out of 5 frigid airs then stopped and wouldn't even try to do the rest. 

I've been really enjoying this game but since the season pass update, trying to do stuff has been poor. Especially challenges and tasks, along with constant crashing.
