Garmin connect suddenly not recording load and training status

All my activities are there. But they are not showing up in load and I have lost training status. It says it requires at least 2 weeks of data. Same problem on watch, Garmin Connect and Windows

That can happen for example after a reset of the watch to factory defaults, after downgrading the firmware, or in some cases of firmware upgrade gone wrong. You will also not get any training status if your last VO₂max value is older than a week.
