It was working fine the first few weeks but then it stopped connecting to the app. It's an iPhone 7 attached to the remote or by itself. The remote shows it's connected so it's only having trouble connecting to the app. I've updated to the latest firmware and the iPhone is up to date too. I removed the micro SD and it didn't make a difference. What else could be wrong?

Hi Parkloop, sorry for the trouble. I would suggest you back up your files and sync your flight records and then reinstall the APP. You can also try a different cable or mobile device so that we can isolate the issue. You may check on our recommend devices below for your reference. If the issue persists, please let me know. Thank you.
