I used to like, even love this app. It was great. Now though, every time I add an event on my calendar an ad comes up and stays there until it is finished. It's awful! So far the ads have not been inappropriate, just annoying. I don't think that going to the pro version would fix this. I don't even know how to find the pro version to purchase as it doesn't show up in the play store. Super frustrating. I don't want to find another app. I just want this one to work without the silly ads.
