Can anyone help with the same problem for current Opera version and most recent Windows 10? That is the path to the files to be deleted?

PS: Removing "c:\Users\<username>\AppData\Roaming\Opera Software\Opera Stable\Local Storage\leveldb*.ldb" does not help with getting rid of activity from old Android device, it i still there.

Same problem on Windows 10 Pro with most recent updates, latest NVidia drivers and Opera 54.0.2952.64.
Any official comments from developers?

+1 here. Useless when designed to pair only 2 devices.

Windows 10, Opera 42.0.2393.94 - same story.
Devs, please fix it. Workaround is not a fix.
