Hello, I have been using Outline+ for a few years and it's my favorite note-taking app. However, recently, when opening the app for the first time after every update I get a message to log in to iTunes Store and enter my password, although iOS settings show that I'm already logged in. Next I get a message about disabled backup, then warning "Cannot connect to iTunes”, finally message that "this copy of Outline is damaged (...)" and the app crashes. Sometimes I can get it to work normally, but it doesn't feel stable. I wonder why Outline wants me to enter credentials to iTunes, and is difficult to get running.
I have Outline+ 22.214.171.124, iOS 9.3.2.
