Hey there, I’m sorry that I’m just now getting to this. The black screen you’re describing sounds a bit like lag… maybe it’s just taking your internet connection a second to download the images? Can you try using a different connection to test it out? Alternatively, it could be the device you’re using (or maybe the DCUI servers were being wonky at the time you posted this).
As for the out of order panels, that sounds like an error within DCUI. You can report those to our MASTER TOPIC: DCUI - Submit All Comic Book Errors HERE! topic so we can add them to our list of comics that need to be checked out and fixed. Sorry for the inconvenience!
Any other issues I can help with? Just let me know!
