I tried removing and re-pairing the car and also selecting a different model. Both times it said it couldn’t access my Skoda account so had to continue un-paired (which is why it can’t read the battery info etc. from the car).
I managed to get into my Skoda account via the MySkoda App, logged out and in again to make sure I had the correct details so it’s not me giving the Ohme App the wrong info.
Hopefully Ohme will sort it out.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
