Brave Sync Android Not Working

I have 2 correct devices showing in the sync chain on 2 different phones (Old & New). Oneplus A3003 & a Pixel 8a. What activates the sync? There is no button, should it happen automatically? Is it possible or are there incompatibility issues/a bug. Please let me know as much time has been wasted looking at the issues & fixes, & trying to figure it out.
