Hi,
I have missing and wrong training status and training load in Garmin Connect Web and Android (marked in arrows in the screenshot below). It started about two days after Garmin fixed the training status outage in their Connect platform. My watch (Forerunner 645) displayed valid training status and training load on these days, but they are missing in the app and on the web. Furthermore, the training load dips (accompanied by the blue recovery training status) are wrong. My watch showed a training status of Maintaining and a stable training load on these days. I also looked at my activities in the 7-day period and concluded there should not be any dips. I train consistently on regular days and hence my training load is always smooth and stable as can be seen prior to the first missing point.
