The last time I wore a HRM strap was before 15.19 and it always worked fine. Running Dynamics w/out the HRM strap also work fine. However, this morning the 955 only recorded HR and respiration rate from the HRM strap. Everything else was blank. I did structured intervals configured on the the fly (on watch) as I walked out the door which is also normal. I'll try the strap again tomorrow (easy run).

I just looked on the phone GC app, and it shows I got about 20s before it all went to nothing.
