Sounds like us. I contacted EA and was told my friend had to open a ticket to troubleshoot from his end since he was the one getting the error message, but when he did, he was promptly told it's a PSN Share Play issue. So we waited till the next day, tried it again, then re-contacted PSN, as we had contacted them first, and they walked us through some steps that we'd already tried the first time that didn't work, then were told to contact EA again because Share Play was working otherwise, then also told by PSN to just wait it out and hope it starts working again.
I'm not happy you guys are having issues, but I'm kind of glad my friend and I aren't the only ones having an issue.
We both bought the deluxe early release version and yeah, like I said, it worked fine until Saturday, so I don't know what happened on Sunday.
From what little I've been able to find on the Internet about this, it's happened in years past with other games but seemed to be fixed mysteriously a few days later without any official word that I saw. But so far no luck on this end. We haven't tried yet today.
