It is frustrating that the 955 does not support Stryd power natively. As a long term Stryd user I really hoped this would be the breakthrough moment. But no. To add to this frustration, I have now discovered, after working with Garmin support, that the source of the post activity battery drain on the 955 is the Stryd Zone connect IQ data field. So I've had to delete this and now cannot get the Stryd power figures on the 955 at all. So rather than a step forwards, it currently seems the 955 is a step backwards with Stryd compatibility. Hopefully this will all be resolved soon.
