Its a great app I used for years. I was ok with ads, but the full screen can't be immediately banished ads make it unusable. When I need Calendar info, I need it RIGHT NOW. I'll give it a couple of weeks but if it doesn't go back to discrete corner ads I'm out. Edit post response: I'd have paid a couple of bucks for ad free version, because it is better than stock Calendar. But its not 7 bucks better. So if you're not going to remove full screen ads, after years of using, gotta say buh bye...
