Bad braille transcription in ADE with NVDA

Hello,

I've bought several books with an Adobe ID and I can't access them properly in ADE with NVDA, neither voice or braille.

It ramdomly inserts spaces in text and makes it truly unpleasant and difficult to read.

I even tried a regular PDF without password protection : it works perfectly in DC and horribly in ADE.

Is there a way to make ADE truly compatible with this screen reader, export the PDF, create a bridge with DC ... or any workaround ?

Thank you.

Vivien.
