Sheeran had previously limited his activity on Twitter, saying that he could not cope with the online hate directed at him.
His role in Game Of Thrones involved just two lines - "It's a new one", in reference to a song that Maisie Williams's character Arya Stark heard him singing, and "Worst place in the world", about King's Landing.
But fans of the show had complained about having a celebrity included in a scene.
Much of the criticism was around the fact that there seemed to have been little attempt to disguise his cameo - whilst other artists such as Coldplay drummer Will Champion and Gary Lightbody of Snow Patrol were more difficult to spot in their scenes.
Sheeran's scene also left an opportunity for him to return in the next episode, although he did not appear in the trailer.
Co-showrunner David Benioff previously explained: "We knew that Maisie [Williams] was a big fan of Ed Sheeran, and for years we've been trying to get him on the show so we can surprise Maisie. This year we finally did it."
It was recently revealed that Sheeran will next make a cameo in The Simpsons, as a character caught up in a love triangle with Lisa Simpson.
