I think I had asked you about this before, but is there a specific reason you are so sure about AV?
I snip quotes from time to time, or remove a spoiler to make it easier to see the thing I an replying to. Maybe bold some text for emphasis, but this is rare. I might also add a bit of context, if the original post had a quote in it that got lost. (Things like "Quote about AVs claim") But the thing you probably mean is a technical problem.
Not an IPhone in my case, but another kind of phone.
