Trouble Sharing Workout Details w/ Training Peaks and IMI

I managed to upload my first IMI workout (Ad Hoc using iPhone) to Training Peaks night before last. Last night I did my first workout created on the IMI web site. It transferred just fine to the iPhone, but it will not transfer the completed workout to IMI, Garmin Connect, or Training Peaks. I’ve checked my account settings and they are correct for each account. Curious if I’m missing something else in the settings which is preventing this.
