Apologies if this has been covered elsewhere, I couldn’t find anything though. 
I’ve just moved from a Superb to an Enyaq and the App for the Enyaq is - basic.

The Superb version had very useful functionality such as linking calendars to satnav, lock doors etc but none of that exists on the Enyaq version.

is anyone aware of likely updates to the app?

From the android store reviews:

Hello Mr. XXX, the services for Enyaq iV are gradually being developed on a completely new platform. That is why the main charging and air conditioning services were developed first. Unfortunately, at the moment we cannot guarantee the availability of additional services for vehicles that have already been produced. Your MyŠKODA App Team

Its because this is on a new shared VWG platform (MEB - 2019), so you've come from a well established platform (MQB - circa 2012 first iteration) to a brand new platform. This needs to have the functions available for the app to call, which I'm guessing are just not there yet. The best indication of what is coming is to keep an eye out on the ID3/4/5 cars as they are the same platform and VW seem to be pushing on with things quicker than Skoda. Clearly from what the app developers have said, they have no clue on new features that may or may not appear either.
