Great exercises - app is buggy

I want to start by saying that I love the exercises in the app. They start relatively easy and becoming increasingly more difficult as the program progresses. My results have been great. My issue is the ongoing bugs in the app. Ive had to resent numerous times and this morning after opening the app it tells me its a rest day (which yesterday was a rest day and today was a supposed workout day). Really annoying
