For some reason (randomly, I think, just to tick us off), it gives us the HTML box with no option to go back to the regular formatting box.
It happens CONSISTENTLY on iPads, randomly on my Android, and randomly on my Mac. I haven't noticed it on PC but I don't often post from PC as my only PC access is at work and I am usually supposed to be working.
Until the actual techies get it fixed, you can jury-rig a fix by inserting line breaks yourself. If your box is yellow and not white, and you want a paragraph, insert these things: < br >< br > (minus spaces) and you'll get a paragraph like the ones I have in this one.
Hopefully the techies will fix it for real soon.
(I figure a lot of you already know this, but maybe it'll help someone... maybe...)
(ETC some wording that made no sense.)
