Score Attack results didn't load

I’m trying to complete each of Halo 5’s campaign levels with the Iron Skull on Legendary difficulty, I had already done Osiris and Glassed and was doing Blue Team which is pretty tough to put up with the slog. I had Score Attack on so I could have the ending scoreboard to take a screenshot. Took me about 30min to do it, along with a few more failed attempts beforehand involving getting stuck with plasma grenades and useless AI. I managed to finish the level the way how I wanted it to flawlessly only to be met with the message that my results couldn’t load. It’s really devastating how I put so much effort in only to get a big cop out from results loading. And it sucks because it can’t load again since there’s no way to search up campaign match history internally and externally. Even though I am happy for beating this level as part of my challenge, I will now be frustrated in the gap of my screenshots showing success of my Halo 5 Iron Campaign and there’s no way I’m repeating that level just to get a damn screenshot.
