Not Synching Everything Between Devices
I've imported all bookmarks, login data and everything else from Brave browser to Firefox and I can use Firefox as if I'm using Brave. All my data have been imported. Until here everything is ok, but I switched my pc and started to use Firefox with my Firefox account and enabled sync. Boookmarks and login information that I saved before importing have been synched but the imported data haven't been synched. So I can't use any login info or bookmarks from old Brave.
I've double checked sync options and see that everything that can be synched are checked.
What can I do to fully synchonise my browsers?
