Problems with storage, reading and writing files after Android 10

[Taifun]

@Luke_Duncan

simply writing/exporting to the app's private directory does not help me

if you store the files in the application specific directory, your app still will work after App Inventor targets API30 in late 2021

@Luke_Duncan

if I exclude the slash from a file reference (i.e. 'file.csv' instead of '/file.csv') the app will utilise the app-specific private directory for that reference.

no, this is the private directory... the application specific directory is different...

I cannot access the app-specific directory on the device

you can, you only have to use the correct path or an extension, for example the file extension (there are also other extensions)
