I want to make a web map that includes a relationship class. Ideally, the users of the web map should be able to edit related records. I know that ESRI recently added the ability to "Show related records", but I don't see any capabilities to edit related tables in any way. Has anyone found a workaround for this? Is ESRI planning on releasing this functionality at a later date?

You can also edit and add related records using the Crowdsource Manager App:
