Are many-to-many relationships supported in AGOL or Portal

[KevinCapone__GISP]

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.
