Custom Workout's no longer showing under 'Training' on my activity profile

I went today to start training for my 2025 SUP race season and uploaded my workout as I have done many times but when I went to the 'Training' tab there was no longer a 'Workout' option to select the custom workout i had uploaded and synced.

Does anyone shed any light why the 'workout' option is no longer there?  it used to be there.  I am using the SUP profile.

My watch 'updated' itself the other day and can't wonder if this is linked.
