STILL Not compatible with ios11, out for money only

Bait and switch: Agree with other reviewers: yes with paid version there are still popup ads when you open, and yes this is a simple app, which cost more than similar apps..but my other very complicated apps were updated immediately for ios11...this one we are STILL WAITING FOR..where is the support? Well guess what? Their ad-bloated free version was updated almost a month ago. Unreal. It took forever just to get a percent key in side by side. Sad I spent money on this greedy developer.
