Rules in Firebase database revert to original

Question

I'm developing a proof-of-concept application, and thus my security requirements are low. I therefore changed the access rules to public access:

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

This works as expected. The problem is that after a few minutes, the rules change back to default values (auth required) and I get an access error "Error: permission_denied at /cases: Client doesn't have permission to access the desired data."

Why on earth is this so?

Thanks.

You must edit database.rules.json in your IDE then save it then deploy it.
