Frequently will not connect
This app is great when it works. The problem is it only works about 20% of the time. It will search and search for the printer that it was just connected to moments without finding it. To make things worse, you can’t go into setting while it is searching to disconnect the printer and reconnect. It just locks up and never connects. Sometimes it will connect later on but it is fairly random. I have had success deleting the app and reinstalling, but it eventually looses the connection. This is a widely know issue and no one has fixed it.
