I have the Edge 1040 and recently got a new bike (Aeroad 2024) with a 4iii power meter. I have several other power meters paired with no issues. However, with this one the Edge keeps popping up with the attached screen (yes, my display needs to be cleaned) :-D
It doesn't matter what I press - it keeps popping up 15-20 times at random occasions (needless to say this is pretty annoying). I have tried removing the sensor and pairing again numerous times.
I suspect this is an issues with dual-channel sensors but very annoying nonetheless. Both the Edge and the 4iii sensor is updated.
