I am told currently the zoom feature of the mini map is not available on Apple TV app. This would be a nice feature to add.
I would LOVE to be able to change the aspect view on the ATV mini-map, also. It seems to randomly change from directly overhead to an angled aspect with various updates, but is unchangeable in-game, though it can be changed in other iOS apps (iPhone, iPad). I’m not sure why Zwift doesn’t allow this, but it would be a great addition,
