I’ve bookmarked a few of my matches and they can be viewed on the day of. But, after that, they are not accessible. 
Unfortunately there are issues with Theatre. I suggest filing a support ticket through waypoint, and list all the specifics on what went wrong. Also, check out the known issue page, although I don’t think it’s been updated in a couple weeks. I’ll also mention, all of your theatre content will be reset on Dec. 8th.
Thanks for the info.
