We have new relase notes for 9.24 and it states:
Added support for Run Power when paired with a compatible accessory.
Does that mean that finally Stryd may be used for native power fields?
I wish they support Stryd. But, that's not the case. The compatible accessories are HRM Pro, HRM Pro Plus, HRM Run, HRM Tri and Running Dynamics Pod. I have both Stryd and HRM Pro and tested this myself on the alpha version 9.22 on my Epix 2.
