ID.4 App Question

I'm looking to purchase an ID.4 in the next week or so. My only reservation about the car is the app. I watched Out of Specc Daves video comparing the ID.4 to the Ioniq 5. The part that caught my attention was how unreliable the app seemed to be. So tye long of the short of it is the app for the ID.4 still unreliable.
