Problem with July 30 2020 Version: nb184 no longer able to write and read files

Note, this will only work for another year or so. Starting with Android 11, Google will no longer allow apps to read outside of their app-specific directories.

I checked this with my testStorage_API29.apk (→ GoogleDrive link above) an a Google Pixel 2XL (runing Android R, 11 Beta). It works without any issues (using TaifunFile & EFile extension).

The folder

/storage/emulated/0/myDir

is created and the text files are saved in and read from this folder.
