I started using Opera for Android version 36.2.2126.102826 on my 2013 model Nexus 7 tablet recently as Firefox was running like a turtle in molasses and taking my launcher down with it. While other forums load fine in Opera, POTN doesn't.
On logging in to POTN, as the page loaded it showed the purple (?) button for unread threads to the right of the PM icon as usual. Then that disappeared. Then when the page finished loading it came back, but clicking it did nothing.
So I came to this sub-forum to report on it. I clicked on the Start a New Thread button and got a message saying, "OPENING EDITOR Hold on... Security token failed/expired. Please reload the page and try again." It doesn't matter how many times I reload the page, I get the same message when clicking the button.
I'm able to use the forums by clicking the Followed+Own link, looking for threads with new posts, and clicking the New link. But it means I have to use two different ways of reading the forums, one on my PC and one on my tablet. If it can't be fixed, it won't put me off using the forum, though.
