Hi,
Recently when the new firmware came out I installed the 9.0 firmware. Everything was fine until then. Sometimes the unit does not connect directly with my heartrate sensor, turning it off and on in the settings will help to connect, but now my Assioma Favero Duo power meter is disconnecting after I think 15 minutes. Turning it off and on in the sensor settings menu will not help. I have to stop my pause/stop my activity, press the power button, wait for a couple of seconds, turn the unit on and then I can finally connect to my powermeter again.
Garmin please publish the edge820_880.gcd file so people can downgrade to get everything to work properly again till the new bugs are fixed.
Kind regards,
Lennart
