Some inconvenient issues.
1) Since you have to join the wifi manually coming from the camera, sometimes you are asked for the password to be re-entered. Just tap cancel and that fixes it. But annoying you just can't tap the wifi and get on. I don't have this problem with other items like a drone that sends out a wifi signal.
2) You have to double click the home button and force quit the app to have it connect to the camera almost every time you use it. If I leave the app for a moment and go back, I then have to close the app in the app switcher and then reopen it.
