Braille screen input and iOS 13

I hate the bubble sound when using BSI in iOS 13. I find it annoying enough that I haven't yet updated my primary iPhone. I also still notice, on my older iPhone that I did update, that I still seem to have difficulty getting BSI to recognize when I flick right for a space. Sometimes it takes me 2 or 3 attempts to get the space to take. I type constantly using BSI, so this is frustrating to me. I've sent 2 emails to Apple's accessibility department and haven't received a reply.
