Garmin Coach keeps canceling workouts and turning every day into a rest day

I setup the Garmin coach to prepare for an upcoming Marathon, 5 days of training per week (rest days on Monday and Wed)

The first 2 training days went OK, but after that it would never let me do any more training. At the beginning of the week it will show me the upcoming runs for the week, but when the morning of the day arrives I find that day's run had been canceled and I see "today is a rest day" instead. It has canceled 3 days in a row now even though my training readiness is 100%, and all my other metrics look good.

A month ago I used the Garmin coach to prepare for a half Marathon, and the feature was phenomenal, never glitched like this. I have the Fenix 8 47mm solar watch, and the Garmin Connect app on the Android Pixel 10 Pro.
