My bank only supports Zelle in the app, not on the web interface, and ever since an update a few months ago the Zelle part of the app suddenly won't load at all on GrapheneOS. There is no fix. So now I can't directly send and receive money through a bank without waiting days or paying a wire transfer fee, because in the United States this ability is monopolized by a private corporation's proprietary service, which can only be interfaced with through one's closed-source banking mobile app.
