I have an APH Mantis Q40 so I am affected. Just so people know IOS 14.4 fixes major security vulnerabilities so it is crucial it is resolved ASAP. I've written to Apple Access and I'd encourage others to do the same if they are affected.
Connection issues for the Mantis and Chameleon braille displays
The following is taken from a warning notice issued by the American Printing House for the Blind:
The basic issue is that once you upgrade to 14.4, as soon as you lock your iPad or iPhone with the Mantis or Chameleon connected, the braille display will not automatically reconnect once you wake the device back up. You can force it to reconnect by leaving the terminal and reconnecting from there but then you won’t get braille. The only way to get braille back is to toggle Bluetooth on the iOS device but the issue will happen again as soon as you lock your device or it goes to sleep.
Another way that this issue can manifest is if you don’t lose your connection but use the braille display to wake up the iOS device, you can successfully wake it up and regain your connection but you will stop receiving braille. Regardless of how the issue appears, it is best to avoid it altogether by not upgrading to 14.4.

How often the bug occurs
I am required to upgrade my work iPhone to 14.4. If I relied on Braille in order to use my iOS device, I would be in serious trouble. Hey, Apple, accessibility is not a toy; it is serious business.
I am having this problem with the Brailliant BI and the E-Reader in beta with Humanware. I am a a beta user also with my iPhone, and will update when I see a beta that fixes this most serious problem.
I was advised by Apple support not to downgrade because of the new security that was put in place with Ios 14.4.
I am also having this problem with Ios 14.4 and the Braillient BI. Also with the E-Reader in beta from Humanware.
