Blizzard Collections not working on Website

Not sure if this is where I should put this but I cannot get a lot of my friends collections page on armory to load up. It just says “oops something went wrong”. I can see their toon, ilvl, gear etc but when I go to Collections it wont load. Ive tried on 3 different browsers, cleared cache/cookies etc and still they will not always load the page for collections. Anyone know why please?
