Well it has and is hasn't. If I follow the link for MySkoda from the Skoda website to the Google play store, the app details show an "updated" date of 4/12, and it has a new icon. The version number, though, is still the same (3.5.5), but the "new" version doesn't behave in the same way as the "old" one after uninstalling and re-installing.
This is what Skoda emailed me last week: "The new MyŠKODA application will be easily recognised by its all new logo and will be available on Google Play (after 04/12/2020) and Apple App Store (after 10/12/2020) as an update of the current ŠKODA Connect App." So we do have a new icon in the Play store, and if you were to (re)install MySkoda it now installs Skoda Connect (which itself has a menu item linking to the "old" MySkoda app which functions as expected and doesn't launch Skoda Connect!
All a work in progress I think!
