Hi @MrDogeBro,
If you check our Process for reviewing classic confinement snaps, the access to arbitrary files on the system isn’t typically a justification for classic. Strictly confined snaps can access users’ files with the home and the removable-media interfaces (which is almost always sufficient). personal-files and system-files may be used as well if needed.
Could you please try them out? In case you are not familiar with it, I suggest using snappy-debug during troubleshooting. It will recommend interfaces based on the behavior it observes in your snap. Feel free to add here any further question you might have.
Thanks!
