Sorry to be a pest.. I love the old text editor and that we have it back on mobiles (for now), only thing is, with it an old issue came along for me ^^' on occasion (as in so random I have yet to determine a logical explanation or reasoning but have failed to find one) when I tap the box and start to write, it hasn't properly selected it.
To explain in more detail, I tap the box, a cursor doesn't appear (if I remember correctly, or it does appear but doesn't blink..) but the keyboard does come up. I tend not to look at cursor, but start typing right away.
What then happens is the text is grey, and upon inspection of the bbcode buttons, they are still greed out as if the box was never selected in the first place or deselected after writing. Autocorrect and the like are automatically off the table in this half selected mode
The only way to get all the functions back to normal is to tap next to the text box, and then back on the text I was writing. (Then the text goes white, and the buttons get their correct colors and functionality again)
But I must say I prefer tapping a text box twice, over having to go back and edit in capital letters after every enter ;)
Edit: this happens on an iPad 3 in Safari, latest iOS version
