Thanks for the suggestions, unfortunately I can't undo those transactions because I already tried to disconnect and reconnect the Square app, which was Square's solution to my problem. I was able to disconnect, but now I can't reinstall the Square app. The Connect to Square link is dead, and searching for "Connect to Square in the QBO Find Apps tab returns nothing. If I search for just "Square" I get a result, but it's labeled as Beta and the install doesn't work -- I either get a message that it's not allowed at this time, or I just get a spinning wheel that never progresses.
