I just released a new version of my app https://flathub.org/en/apps/org.fkoehler.KTailctl which requires a new permission (network access) due to a new feature (fetching user account avatars from an url). A reviewer has rejected this change and thus blocked the release. He simply posed the question why this is new permission is needed. Unfortunately, I cannot find a way to reply and appeal the review. I fully subscribe to the idea that flatpak apps should have as little permissions as possible ...
