I’ve only had this happen while doing group workouts, and during group workouts I use BT headphones attached to my Win10 laptop for both music & group workout audio. In the last two group workouts I’ve done, my H3 erg has dropped, either causing me to try to spin somewhat furiously to keep on target power or completely miss a sprint interval. Both times the erg comes back at the start of the next interval step.
Because it has happened during group workouts, I’m wondering if it could be my BT headphones causing interference. After a group workout this morning I did a brief workout alone and it happened again, so it doesn’t seem limited to just group workouts, but I still had the BT headphones connected to my laptop. When I’m riding alone I usually use corded headphones for my phone or Roku remote, and don’t sync any headphones to the device running TR. Curious if anybody else has had this problem?
