FIRST: My Microsoft and Xbox account settings are to show content to everyone.
SECOND: I am not receiving any error notifications.
My screenshots from the last two weeks show up in my profile, when I share them, on XboxDVR.com etc etc but when I go to link them in Halo 5 to my maps, they simply are not there. Screenshots from approximately two weeks and longer ago are there, but none will show up in the Link list since then. I’ve tried sharing them to my feed and groups to see if that would “refresh the database”. Other than that, I do not know what I can do short of reporting this Halo 5 glitch.
Please help. I spent 1.5 hours taking screenshots for my maps in Halo 5 Theater, and I can’t use any of them. I’ve spent Countless hours creating quality maps. My hard work needs to be paid off by being able to showcase my Halo 5 maps as intended, by providing users with screenshots that show their quality.
This has been happening to me too! but only recently. It sucks because after spending so much time on a map, you can set a picture for it. It also really sucks because no one joins custom games that don’t have pictures 
So far, google hasn’t helped me either
Yep I can no longer create any new maps because of this. Due to how NOBODY gives new maps without screenshots a chance, pics or it didn’t happen I guess.
This bug has been reported by many and 343 are working on a fix. They believe it is due to an issue with the new system update and how they haven’t updated their systems to recognise the new DVR.
(Try not to duplicate threads already posted by others).
In the mean time you can have a try at a work around that might work.
Have a try of the work around I described on this thread: https://www.halowaypoint.com/en-us/forums/e0d9938206f04a598ce84f2c8cadce02/topics/linking-screenshots/4639fce4-cfe2-49bb-8739-c991e9c65dcb/posts?page=1#post4.
If that doesn’t work then you’ll just have to be patient (or attempt to uninstall that system update).
