Navionics and a new phone

[Refueler]

I think you are right, I'm sure Google link your phone ID with your iISP and control a lot of apps availability, especially those that are zoned, it renders VPN's pretty much a waste of time now.

I think its far simpler than that ..... they link your phone / tablet you downloaded the app to - to the Google Login you use.

Example : I changed my IPTV Android box other day (the TV is not a built in SmartTV) .... old Android box was starting to lock up when watching F1 etc.
I went to download F1TV to the new box .... but Google showed I had reached maximum number of units to view the app on ... a list of the Brand Names / Model ID's of each. It did not matter about ISP. I deleted old box from list and it installed to the new. I put my Login into the F1TV app on new box and I had my full subscription operating fully .....
