I've been re-learning Braille in order to take advantage of BSI on my iPhone. I probably won't do much Braille reading, but BSI will help me enter text faster than with the on-screen QWERTY keyboard. It was all going quite well. I took a break for a few days and just tried to use BSI again. I am now unable to reposition the dot locations by tapping the right three fingers followed by the left three fingers. That was working fine earlier. I'm running iOS 13.5.1 on an iPhone 8. I've tried power cycling the phone without any effect and this seems to be an issue independent of the app I am using. I am unaware of having changed any relevant settings. It is possible that I haven't used BSI since updating to 13.5.1. Any suggestions, please?
