I cannot find any information regarding if many-to-many relationship classes are supported in ArcGIS Online or Portal. I have one-to-many relationships working fine, but I cannot get many-to-many to view related records. Any help would be appreciated.
Hi Kevin,
I saw a document from Web App Builder states that Edit Widget works on many to many relationship classes, which means many to many relationship is supported.
