Pricing for auto-assist?

I own a tado v2 system, I've never had to pay for geofencing. The app keeps nagging me to upgrade to the new v3+ app and it shows a screen assuring me that I won't have to pay any extra charges.


However - if I click the "What is Auto-Assist" link it takes me to a page on the tado support site that clearly states auto assist is purchasable for a "monthly or yearly subscription"!

So which is it?!? As things stand tado is giving out contradictory information. I'm not going to pay for an "upgrade" that locks me into charges for a feature that is free in my current setup and only reason I bought my tado system in the first place.
