Hi
Thanks for getting back to me. Couldn’t find how to DM you 
So, I’m using the calendar ok in finding a workout of interest, and then selecting Schedule, and then navigating to a date to add it. Selecting a specific time isn’t possible, or very accessible anyway with VoiceOver, but that isn’t important.
So, In the evening, I can pre-select a specific workout for the next day this way.
I can then go to the calendar, double tap the activity on the day of the month I previously selected for that workout and simply do Load Workout, and check I’ve devices attached and pedal to start, brilliant, it works well.
I found that if I turned VoiceOver off to show that cal to a friend for example, it causes the Calendar Welcome screen to appear which only offers a ‘Next’ button that does nothing. You have to kill the app to resume to get anywhere.
You can test this by just ending VoiceOver and re-starting it on the Calendar tab, and see if the Welcome Screen pops up.
I’ve got everything enabled in the Settings, including Narrative Notes and interval sounds etc.
So, I get the motivational announcements as well as the current, next and subsequent interval descriptions announced at the start of every interval.
It all works well, and as long as I don’t switch media / messa about with music play back choices during a workout, get that all set up first, then my workouts work perfect now.
I love the ‘Pedal to resume’ feature for when I’ve stretched myself too much and nearly broke my spirits
A quick swig and continue to the end !
I’m in touch with WattBike themselves to address inaccessibility issues with their native app, preventing basic pairing from the start amazingly for VoiceOver users, and in an email exchange with Ming from TR to tackle some of the text edit box / Plan Builder issues.
Many thanks again
