Brave Sync deprecated version on a device that's been clean-reinstalled just after a brave update(?)

Ok so my problem here is that i have a deprecated brave code that i have been using since April 11th 2022. So the story here is that i was doing a custom OS testing that i am currently new at first i tried “LTSB 1803 XOS” and it didn’t work quite good so i putted my brave sync code and it’s still working fine logged on into my discord checked a couple channel downloaded “ggOS 21h1” converted it to ventoy into my usb clean-reinstalled again and downloaded brave and apparently my brave sync code has been “deprecated” for some unknown reason? i don’t even know cause the brave installer was still the same yesterday and just after i installed XOS and now it’s been deprecated? Please reach out to me if you need further information cause it’s not really clear and i’m in a rush right now and currently nervous that i have lost all my saved password in every website i have used in the pass cause i have nothing right now

Apologies but I’m slightly unclear on the steps taken here. As I understand it, you had a custom OS installed, installed Brave on it, set up a Sync chain on it and everything was fine. Then, you installed a new OS, installed Brave on it, then used that same Sync code from the previous installation to add Brave to that same Sync chain and, after attempting this, you saw the error you’re describing.

Is that correct?

I have this problem, do you know how to fix it?
