The Open Tabs sync feature is now available on Edge for Android. Just received it yesterday and it works great!
This is the feature in action:
Open Tabs from my PC on phone
Similarly, the Open Tab entries from phone are also synced to the desktop versions:
Tabs from my phone on PC
This is a great addition to Sync and will make picking up sessions between devices easier and faster. I will also recommend adding the ability to delete the open tabs on a particular device if I open it on another, say for example if I open an open tab from my phone on my PC, the tab can be deleted manually by us.
