I hope you don't mind but I queried a few email lists with this problem. Sharing the most helpful response here in the hopes that someone with the same problem stumbles upon it.
" This has to do with how the braille translation buffer works. The only way I know of to completely get rid of this problem for iOS, iPadOS, and Android is to set the braille display input to computer braille. When using computer braille, it works exactly the same as print (QWERTY) typing; one symbol per character.
The absolute worst is using contracted braille. UEB is better than older braille contraction systems such as BANA which has over 300 exceptions to its contraction rules.
IOS / iPadOS uses the same braille entry buffer whether one is using grade 1 (6 dot), or grade 2 (contracted) braille. Therefore, if the author insists on using either form of braille input, it is necessary to press space, or wait a couple seconds, for the buffer to clear. Moving the editing to any other location in the document before the buffer has been cleared will cause the sort of editing issues which are described in the email I am replying to."
