Okay, I haven't thought much of it until a post I just made, but I'm having a lot of problems typing on mobile, iOS specifically.
Some of it is weird little stuff. I just pressed return to start this paragraph, and it places the cursor right below the last line, with Shift on. I press again to start a second paragraph properly spaced from the first, and Shift comes off, and I'll have to redo the start of the paragraph. Like I said, minor, so I didn't make a fuss.
But if I try to delete the first letter of a line like this, it does that AND takes me back an extra line.
What made me finally crack and post this is when I was writing a long post, I'd highlight text and italicize or bold it, and chunks of other text around it would disappear. There was something where more text disappeared as well, but I didn't catch what caused it. I think when I tried to cut/paste a separate block of text?
Just a whole lot of weirdness on the whole.
