The Ads!
The app is unusable. Every time I select a button, a very long ad pops up. It is so bad that I cannot even get through one sketch to see if it’s worth paying for. If it is this bad now (at the point where they’re trying to convert me as a paying customer), I cannot imagine the charges users will incur in-app. Literally not worth the time and patience it takes to assess if it’s worth a few bucks.
