Fitness+ activities missing

I went to do a strength workout this morning using Fitness+, only to discover that ALL the strength activities were unavailable to me. I am also missing the Yoga and Hiit sessions too. I can see them in the “new this week” and “try something new” sections, but when I click on them I’m getting an “unable to access Apple Fitness plus at this time” message. The other activities are working fine.

tried all the obvious, including deleting and reinstalling the app. Anyone else having these issues? And has anyone solved them?
