Alt12 Apps is very interested in making the Ignore feature even more accessible by adding an "Ignore User" button toggle to a user's profile on the app itself. We hope to be able to provide this enhancement in a future update.
In the meantime, the web version provides a way to make use of the Ignore User feature. Once triggered, the setting will automatically translate to how your mobile device's app works with the Community feature. For more information, please see one of the knowledgebase items on "Ignore User."
