RESUME TRAINING NEVER WORKS FOR ME TACX FLOW

 I can start a video, ride say and hour, stop activity and save. Then next time I jump in the app the video thumbnail will be there under Recent Rides, I select it, then select Resume Training and it will NOT load up the video. This was occurring last winter with my iPhone 12 Pro, and now this year with a 15 Pro connected to a Tacx Flow. Everything else will come up in the HUD but without the video, just a endless spinning circle.

I tried downloading the video first this time so maybe it would actually be able to load where I left off on the route and pick back up, but still no luck.

I just want to be able to ride a route in multiple sessions to do the full course without having to start a route all over again every time. Nor do I want to use the Pause function and come back again later and the ride not count until I've completed the entire course if that even works.
