Apple & Android Account merge?

I have HTH subscription. I have an Android phone. I had purchased an Apple Ipad for HTH and E6 ( not supported on Android ).

I have setup my Garmin account and subscription on the Ipad through Apple. 

I want to purchase a Garmin golf watch. But when I login to the Garmin app on my Android phone, I do not have a subscription. Afraid I can't use both. 

Would like to see the data and account married? 

Its 2022?  Should the subscription not be able to tell that my email / account has an active subscription on any device ( Windows / Apple / Android )? 

This is a big issue if it cant. I will not buy a watch if not. I cant afford to re-upgrade my phone and change to Apple just for this. 

Anyone else have this problem?  Is there anything I can do Garmin?
