The other day on the 8th after the Experimental card was removed I noticed the background was either taking longer to load or sometimes wasn’t loading at all. Just the dark blue loading background. I saw other people having this issue so I assume it’s an issue on Blizzards end.
Just to confirm, did you try repairing the game or even reinstalling? If yes, then I recommend reporting this in #bug-report.
Can confirm same behavior here (southern california) on PS4 across multiple accounts.
Can also confirm the same behavior for my brother in Phoenix (also PS4).
The problem comes and goes, but has been happening for several days. When it occurs, only the blue polygon-shaped background loads (along with all text), but other images don’t load. So, you can’t see lootboxes, or items in hero gallery, or characters on main menu splash screen, etc.
During a 2-hour session last night, I had this happen at least twice- each time lasting for a few games. Most tellingly: it happened to my brother as well at the exact same time. This strongly indicates that the issue is on the server/delivery side, and not on the local console or the particular user account.
