Constantly resets; can't claim reward for completing 8 daily activities.

I've played PvZ2 for several years.  1) For the last 2 years or so, it constantly re-sets.  It happens every time I play, usually just after starting.  It may re-set 6 times or more before it plays normally.  2)  When I complete 8 daily activities, it shows that I can claim that reward, but it won't let me.  The Daisy tries to form, as if it is trying, but just stops.  It still shows that the reward can be claimed.  The more I click "claim" the weaker the daisy gets.
