This aligns with what I have been told and observed also - My estimated delivery is 2023-01-12 which interestingly aligns with previous due date of Azul ace (now est. 2023-01-14) although no changes in JSON yet.My JSON is 16th Feb but when I spoke to Polestar this morning they said that's when it arrives in the UK
Also CS advised me that delivery month shown on web page is arrival month in country and the month shown on app is handover month which may explain why I (and others) see a discrepancy. I have also been advised by CS it’s due in the country first two weeks of jan with handover early feb.
One thing I can’t explain is assuming my cars on Azul Ace I see an entry on their VIN tracker but it still has all blank fields while other people on this forum have further details shown.
