Cannot get it to work... – WhenToPost: Best Times to Post Review

Sunny Lenarduzzi recommends this app, so I installed it on my iPhone 10s Max. Kind of. During the “login with Instagram” process, I entered my Instagram username and password. The app then emailed me an authorization code which I had to enter. After entering the code, a screen popped up with some programmer gibberish that begin with the words “Oautherror code” (or something similar). And that’s all the app would do. I closed the app then touched the icon to reopen it. At that point, the only thing it would do is go to a screen that had the logo of the app on it. It would stay stuck there and would do nothing else. The only option is to delete the app from the phone and reinstall it. I tried it 4 different times and got the same result every time. Not sure what’s going on with this app, but I cannot get it to work. I tried to email the developer at the support link, but the result is a Safari screen that says the link “cannot be found.”
