Sometimes the game take forever to load COOP contents that I have to restart SC2 like few times to wish there is one time that game can actually LOAD. I do have it in SSD and it only happened recently. And this issue only on SC2 but all my other blizzard games, steam games are fine to load too.
Go to tech with this question.
It’s not just co-op. I also have this issue and deleting the battlenet cache didnt help.
