In Windows 11 if you go to Tools/Settings/Sync Choose What To Synchronise there is the item:Bookmarks.
First question please what does this synchronisation exactly refer to, inside Windows 11 or outside of it?
Clicking on <u>C</u>hange… there is the option of Disconnect, again what does this refer to please?
My gaol and quest has been to go to the three bars (Hamburger) icon and delete the various Bookmarks without deleting them elsewhere in Windows 11.
