Not working – Blogilates Official App Review

I have been using the workout timer in the app for several years and love it. It’s been the best timer I have been able to find. My iPhone got updated a couple days ago. I went into the app to use the timer today and it wasn’t there. I didn’t even have an option to purchase it. The app won’t let me sign in either or even purchase the monthly calendar. Please fix this
