Hello,
I have run into an issue within ArcGIS Pro when trying to share a feature as a web layer to ArcGIS Online. As a back story, I have a feature that previously had joins made to the layer. I then exported the feature to a new geodatabase as a new feature layer. I have a standalone table that I did the exact same thing to as the feature layer. I then related the table to the feature layer with a relationship class. This is where I run into my problem, when I try to share the feature layer as a web layer, I am meet with the error messages found in the image below.

I do not have a selection, so I do not know why the error of "Selection layers are not supported" is appearing. I also do not have any In-memory joins as I have described the export process above and then the creation of the relationship class (which from what I have read, is the method to share a web layer with a relationship class).
Any help is greatly appreciated and welcome.
Thank you,
Cole
