Seems like the HBO GO app doesn't allow you take a screenshot, at least the is happening to me. However, it looks like Tormund is alive with Gendry the shot just before it cuts to Lyanna Morning "reanimating".
You are right. I found Tormund with Gendry at about 1:02:05.
Jon Snow also walks past Tormund and Gendry at around 1:06:21.
Ope - saw them again - Tormund and Gendry at 1:09:41.
...I think I saw Tormund yet again at 1:11:15.
And folks...I actually just found confirmation that Tormund and Gendry are still alive after the death of the Night's King at 1:17:57, standing on a heap of dead bodies....and again at 1:18:40....
