Workouts not syncing w/ Garmin Coach

I started a Garmin coach plan using their AI option.  All seemed well until today.  I ran on the treadmill instead of outside and the workout shows up in Garmin connect but is not syncing w/ my training plan.  I've done some searching and it seems like its an ongoing issue.  Has anyone ever been able to find a workaround or has Garmin ever updated on this bug?
