Day four of upvoting every single one of these related threads until WOTC deals with this incredibly annoying issue. It's been going on for at least 3 months now, and doesn't seem to have any rhyme or reason as to who it effects and when. This has made our Arena playgroup extremely frustrated, and we'd all hoped the Khans release patch would fix it. Time to get this some more attention.

Same issue after the Caverns of Ixalan update, specifically when I attempt to Direct Play my friend, after selecting my deck and hitting "Play", it simply spins "Waiting for Server" and eventually says "Unable to submit deck", or displays network related errors. Have tried restarting, changing local DNS servers, verifying integrity of files, etc - nothing works.

I’ve had the same issue since the last update for Caverns of Ixalan. What’s going on, Wizards?

I’m running on my iPad, and the only solution is to kill and restart Arena. This issue seems to occur whenever I minimize the game and come back later. The network connection is not completely restored. Sometimes I also get an error when browsing the store; Arena tells me it cannot retrieve store items, and the store icon is blacked out.

I'm having the same exact issue since the maintenance yesterday
