What happened – Week Calendar - Smart Planner Review

I used to love this app and now I can’t get by the ad for a paid subscription. I have already paid for the app and don’t want to upgrade to the pro. It won’t even let me use the app because I can’t restore it. I now only see the ad for the subscription and can’t see my calendars. Please fix!
