I have had my H9 Max for a little over a year and have connected successfully via Bluetooth on a Samsung Galaxy tablet. Yesterday, that stopped. The app opens but then crashes. I then tried the app via my Samsung phone, and Windows laptop. All with the same result. I reset the H9 Max and also reinstalled the app. Nothing. I was able to connect via USB to my laptop but that’s it. Firmware is updated to the most recent.
