Bookmarks in Favorites Folder Disappear
The bookmarks in my Favorite folder disappear. I can restore the bookmarks by replacing the Bookmarks.plist file via Time Machine. Unfortunately, any action working with bookmarks (creating a new folder, saving a new URL, etc.) causes the Favorites bookmarks to disappear. I'm running Safari on an iMac, Catalina version 10.15.1, Safari version 13.0.3. I'd be grateful for any help with a solution to this recent problem.
