I am working on an Auv3 plugin. Whenever I want to save presets to my app (via AUM), I get the message “Sorry - This plugin has not implemented shared user presets, available since iOS 13”. I can save my presets to the host app AUM, but not to the app itself. Is there already something “ready to use” from JUCE that’s gonna deal with this? What do I have to do to enable “supportUserPresets” ?
