I noticed during tonight’s radio 3DJR that posting (on mobile, at least) is different to how it used to be. On Old Blitz when you posted it went and collected any latest posts. On New Blitz it merely updates your screen locally. You need to explicitly refresh to see if anyone else posted recently.
I thought I was very unloved for the first hour or so… apologies if you asked a question during that time.
Other than that, and one moment where I got a black box pop up to tell me of an unspecified error, smooth. That error went away after about three post attempts.
