Link Nike Training Club App to Apple Watch & Apple Fitness

Hello friends,

I recently tried to link up Nike Training Club app to my Apple watch. From what I understand, once linked it will reflect my fitness activity on both Apple Health and the Apple Watch's active workout tracking (rings). I've loaded the Nike app, connected it to Apple Health on my iPhone and allowed it to write data to Apple Health. All of that seems as normal.

However, I just did a 30+ workout in the Nike Training Club app on an iPad, and none of the information seems to be read on the iPhone watch, or Apples Health. Does a device other than an iPhone or apple watch have the ability to write data over to Apple Health or Watch? I think the issue here is I did the workout on an iPad rather than the phone. All devices are connected with the same Apple ID & Nike user account, so any advice on how to get workout data from the Nike app on the iPad (newest AIR model) would be greatly appreciated.

This question has been asked previously, but the info was sent to a Nike page that's not currently working.
