Ok, the problem must be on my end.
I use an iPhone.
What happens is when I hit the camera button to insert an image I get a page that says "To serve you better and protect your privacy, please set your username."
I'm already signed in, and. When I input "epicxt" I get a "System Message: Network error, please try again later." This has been the case the last two days, although it's been a while since I uploaded photos.
