Why can't ZArchiver access My Samsung A32's complete storage?

[COOL-CAT]

My previous device Samsung A30 would allow ZArchiver to it's whole storage but my A32 won't allow it access the complete OBB,etc files....... How can I get ZArchiver access to the obb files.

PS: ZArchiver is showing the following message when I try to export files to the obb folder 

"This folder is read only"

Android restrictions after a12.. however you can access by an app 'Files' install from playstore..
