Brave synch broken

Hi all, i have difficulties to maintain synch between my 2 laptops.

although they belong to the same synch chain, both share the same synch code, both have synch everything enabled, when i add a bookmark on laptop A, it doesn’t appear on laptop B (and vice versa) Although i have the 2 laptops open at the same time. Lastly Under the device list , they list only themselves - although i tried to leave and rejoin synch chain, it didnt help.

Some other notes:

  • Both of them run same Version 1.34.81 Chromium: 97.0.4692.99 (Official Build) (64-bit)
  • Laptop A runs Kubuntu and laptop B windows 11
  • Both laptops are open and running simultaneously.

Hi guys, no one had the same experience please?
