I'm experiencing a bug that I haven't seen for quite some time:
When relaxing on the couch after a run I noticed that my Fenix5+ was showing random HR values in the area 220-260. Turns out it was still picking up signal from my HRM-Run (which was taken off and left in the bathroom) and alternating between this and the internal OHR. Manually disconnecting the HRM-Run from the F5+ menus immediately solved the issue.
This is something I saw from time to time before (pre-FW6.00) and I remember it was discussed in here at the time as well, but I didn't manage to find that thread. I wonder if this bug might have been re-introduced in FW7.10 ?
Anyone else seen this?
