Cannot Edit Related Tables in Arc GIS Online

[EvanSanchez]

Hi, 

For some reason unknown to me, when I try and configure the popup in arc gis online It will not allow me to select the edit buttons on my related table. They are greyed out. It will let me edit the feature class but not any of the related tables. The layer is being hosted as a feature service. Also when I exported the layer fro pro I selected the "add,update,create,delete" checkbox.  Any help would be appreciated.

I believe you will have to set it up into a Web App builder app and set up the EDIT widget to accomplish this. In Portal you can do it directly but I don't think  you can in AGO
