Hi there! Here's what I'm understanding, and please correct me if I'm wrong:
You've used an app that has its own import/export functionality, made an export, transferred that export to your GrapheneOS device and are now trying to import it into the app, but you can't find the export file when looking at it through the file manager.
Can you give me an example of an app in which this happens?
A screen recording of your setup/process would also be ideal.
Looking forward to your reply.
