To the OP: Yeah, I am also bummed by a three weeks bump-up in delivery time (December here). I understand what is going on; it’s all the same inconvenient.
Not quite as inconvenient as having to order a Google Pixel 6 from France or Germany, then rely on additional service to receive it and forward it to you. Then, if anything goes wrong, the phone goes all the way back through that same route for repairs or rma, then you also have communicate with people on the other end. And, rest assured, both German and French services will unlikely speak English with you.
To the rest: I am also a prospective new FP4-er. Long story short, I want an Android One phone, as my S10 is driving me nuts ever since Janury 2020. I wanted to go for Google Pixel 6, but guess what… Google considers most of Western Europe to be the middle of the bumf*** nowhere. So there goes that option. As a fellow techie, I hope to make do with FP4.
