On a MacBook, I cannot delete the app. When I try, it gives me an error message that it is “waiting to download”. But the app is downloaded and will open a functional account. Apple Support tells me this is a Trello problem and that they cannot help me. Other places on the macbook tells me that it is an icloud sync issue but it will not let me resolve that either. I no longer need the app and want it gone from my desktop but have tried everything that I know how to try.
