Cannot use android/ cubasis folders anymore on chromebook after google update removed permissions

i needed android / cubasis folder permissisions access to load samples to cubasis and to get my master song mix outputted. but chromebook update lessened folder rights so i can not go to that folder and load or copy samples and my master song mix there. is there update or someting to cubasis that let me able to make use from my paid cubasis ? i got the issue with steinberg cubasis now. and google not let roll back updates on chromebook. i quess you make some fix ? cann not sell product if user can not load samples to it or copy files created with cubasis that wich samples area in folder under android/ cubasis that user has no permissions to look files to copy . it was the chromebook update that changed permissions. but you want to sell products still

Maybe this helps…
