What is going on

The app hasnt been working correctly for a long time. Every day I open the daily training section and it says I already completed it and I should upgrade it if I want more training, even though the last time I completed a daily training was a few months ago. I tried waiting it out thinking it must be a mistake but its really not doing anything. Please fix the daily training so that it actually works. Im getting tired of being cornered into that upgrade button whenever I try to do something thats supposed to be free.
