I updated the software on my forerunner 235 today and the up and down arrows stopped working. I had to reset the factory defaults and now the watch won’t find Bluetooth. I tried on my iPhone 7 that is running iOS 13.5 and on an older iPad mini. The Bluetooth pairing just keeps spinning and eventually says it failed. I restarted the watch and the phone. I removed the watch from the garmin connect App too. Now I have a nice watch that connects to nothing. And it is incredibly frustrating.
