I was able to sync from one phone 1.19 (20.07.21.09) to another phone (same app version), but when entered code on macOS 1.12.112 nothing will sync. I did restart Brave and deleted all open tabs, removed Brave by drug and drop from Applications folder to Trash and install again (previous one bookmark was there and all options in Synch checked in). Also reimported the code and left only Bookmarks (default option checked in), still nothing
As a suggestion, trim whitespace after last word in the code, in case someone copy paste
I also can see some data was pulled in Little Snitch
Should it uncheck all tabs when uncheck “Synch everything” ?
