Yes, same here.
When I tried to input what I thought was the VW Order number in (starts 31 ... ) MyVW rejected it as unknown. However the number on my 'Dealer' Order was accepted.
It then showed a picture of an ID.3, I have previously seen it reported that you will see a random picture until you get a VIN number, so no concern there.
Last week a VIN number appeared - I got a bit excited until truth dawned, way too early for an Oct 21 order to come through. Now the Vehicle Details link shows a full spec for the vehicle - it is clearly for an ID.3 ..
So, seems that my dealer order number has 'highjacked' someone elses order for an ID.3 on the MyVW app ...
Worrying as I now can see someone elses VIN ... and 'they' all try to convince us that digital data is 'secure' ....
