Autumn correction and auto capitalising when typing with the Braille display

Braille on Apple Products

when i use my orbit reader 20 with my iphone 7 on ios 13.5.1 as i am in writing this email, i notice that the norma; autoccorrect and auto capitalisation features do not work!
I have now changed for a minute to using the onscreen keyboard and all works fine
i resume on my braille display and the faetures stop working! has this always been a problem or is this a recent bug?
