Owners of the Fenix 8, Enduro 3, Forerunner 955 and Forerunner 970 say their morning Training Readiness shows up on the watch, while Garmin Connect shows no score or says there isn't enough data. It's happening on both Android and iOS, and Gadgets & Wearables reported that sleep, HRV, Body Battery and activities are still syncing normally. One Fenix 8 owner got an 87 on the watch, pulled the metrics file off it and sent it through Garmin Express, which answered that it was a duplicate. So Garmin's servers seem to have the data already, and it isn't being turned into a score.
A number of affected users trace the problem to Connect 5.31, which arrived earlier this week, though nobody has shown the update is the cause. Garmin has acknowledged the reports on its support forum, and a company representative asked affected users to check Garmin Connect Web as well as the app. Several owners say the score appears once they record and save an activity, while reinstalling Connect has had less luck. Until Garmin sorts it out, go by the number on your watch.
