Have you made any security changes that would coincide with the timing of this issue?

I am very happy to use opera as the default browser on my phone.
I have some suggestion for improve bookmark logic.
After a page has been added to the express panel the icon of add to EP gets red like on the desktop version so that it is clear that it has already been added. Another click would open the dialog box for changing the address and name like a bookmark dialog work now.
So far, every time you click on the button, it will be re-added to the panel. And I get a lot duplicate.
And I have to delete all duplicate on my computer.
The same for add to bookmark, the icon gets red after a page has been added to the bookmark.
Do bookmarks like in a chrome, at least make that the opera does not make duplicates.
