Seeks Not Working?
What exactly happens when you try?
They just sit under my Daily games as in the screenshot below. It usually takes just a few seconds from when I set up a new Daily game for it to start... this has been hours

That means no one has accepted them and there were no compatible seeks already waiting to be paired.
No, there really seems to be an issue. I cancelled my unaccepted outgoing challenges made 4 hours ago, created new ones, and found opponents immediately. Then I created 2 further challenges, and the issue persists.
I won't say there absolutely isn't an issue, but there are a lot of open seeks out there and I know they stay in the pending state if there's not a compatible one when the seek is created.

Okay, then why, after years of having my seeks matched within a couple of minutes am I now having to wait almost 24 hours and still no match? It seems improbable.
Yeah, there's definitely an issue. If I open up 5 seeks, one will go through as normal (basically instantaneously) and the others will sit pending forever.
I'm asking staff about it, just in case there could have been a bug introduced. I will say that number of open seeks does seem high.
