Trying to sync my bookmarks and add-ons from my desktop firefox (Mac) with my IOS apps (iPhone & iPad). Have fresh apps on all devices. Have a new Firefox account. All are signed into that account. On my desktop screen, a window appeared notifying me that the devices are syncing with desktop app. And yet my devices do not show my bookmarks nor add-ons from desktop app. What am doing wrong? Seems like a simple setup. Simply not working.
