7X Hunt App; "Back to Start" requires subscription??!?!?!? This was an existing feature!

Hi;

I rarely but on occasion use the "back to start" navigation feature.  This was present on the F5, and also on my F7X pro/solar/sapphire/whatever.

Today, on the "Hunt" activitiy / app, I attempted to use "back to start" - and it displayed a QR code and stated I needed a subscription.!!

This was an existing feature, that I paid for when I brought the watch for many coins. 

WTF?
