Do you fairly regularly have a situation where you cannot respond to a discussion or blog, or even create your own content on your iPad. No rhyme or reason: one day you can, the next you can't. You may be able to click 'reply' and it brings up a box to type in text, and the keyboard on the iPad, but when you type the text is white on a white background and then you notice the 'Post' button isn't there so double-whammy.
I have reported this more than once on the Feedback channel and will do so again as it is happening to me now - I've had to come find a computer to write this. I'm interested to understand in a wholly unscientific and statistically irrelevant way how many people it affects.
