Microsoft Docs describes how you can set an apps sub-area link to open a specific entity view. I can create the Sub Area item, set the Type to URL, specify the URL like so
Url=“/_root/homepage.aspx?etn=<entity logical name >&viewid=%7b<GUID value of view id>%7d”
and check the Parameter Passing checkbox. But after I publish, the Sub Area does not appear in the UI.
I've spent hours trying all sorts of variations. Sometimes I can get the Sub Area to appear, sometimes I can get it to open a new page that shows an error message. I tried adding a Description in the designer, but that repeatedly clears itself. Argh, help.
