I have accounts with three Amazon branches - U, UK, Germany -, all set up with a rather complex password and 2FA. Until about 5-6 months ago Deliveries would fetch my orders automatically from them, then it stopped.
When trying to set them up all anew in Deliveries I get a non-descript sync error and the accounts will not be saved.
Could it be Deliveries has problems with my Amazon passwords, all of which contain blanks?
