Do Garmin cycle training plans sync with 1030 plus

Hi,

I want to try Garmin cycle training plans but I'm having problems getting my activities to sync and reflect the workout.

My devices:-

Elite Rivo trainer

Edge 1030 plus

Forerunner 255

Can anybody explain what has to be paired with what? The watch is paired with my mobile app.

The training plan is viewable on Connect Garmin web and mobile app.
At present I cannot see my training plan on the 1030 but can see it on the Forerunner 255

I did my first workout yesterday using a 3rd party training app and the 1030. I didn't use the the watch The workout uploaded to Connect Garmin but did not feature as completed in the plan.

I can't find an understandable  explanation of "how to".
