today, opera sync is ready
all done

opera mini is the same

not for me
reset two times sync data
I tried a new email for sync
same problem

I used 3 PC
and 3 Android Devices to sync

now, when I logged in on Desktop website, under devices I only see my windows devices
on Android Opera I can see my bookmarks
but when I open a new tab and click in the left corner
no synced tabs was there.
reinstalled, nothing changed
