I have the same question - thanks for posting this. I greatly value this remarkable invention for hearing impaired people and would not ever want to jeopardize the availability of captions for their benefit, but I would like to be able to remove it from my small iPad screen at this time as it interferes with my view of many products.
@MezzieStarr ... Well that was easy!! I couldn't see that unless it was on the dark screen...so l clicked on that and it worked immediately! Thank you so much!! 😊
