Problem with favorites bar

Hi,
no you're not alone,
"show Icon only" currently is not registered in sync servers so every time that Edge insider periodically checks with favorites sync server, it reverts them back.
It's happening for me as well as lots of others that have posted about this before.

"delete favorites" issue is also related. I even lost some of my favorites thinking that Edge automatically synced all of them but I shouldn't have trusted the green icon.

obvious sync needs so much improvements so my suggestion is to regularly make a backup of your favorites into an HTML file from Edge settings: edge://favorites/
or use another stable browser such as Google chrome as your back up storage
