Right now functions like Reports generally don't work with Survey123 or ExB when a hosted feature layer has a database with multiple relationship classes that interact with some of the same tables. Errors in the report widget in ExB like "multiple relationship classes is not supported".
So I can do a view and turn off the tables I'm not interested in. Then the reports can run.
But for once case, where I have three tables where there is a 1:M relationship class between Table1:Table3 and Table1:Table2 and Table2:3... the report can't handle both Table1:Table3 and Table2:Table3 if my report wants to return Table 3 records. It just focuses on the Table1:Table3 relationship, and if I nest Table3 inside of Table2 it doesn't return the records.
So if instead, in my view, I could turn off the relationship class between Table1:Table3, and then use that view for my report, I think that would allow me to specify that I want the report to only focus on the Table1:2 and Table2:Table3 relationship and it could ignore the Table1:Table3 relationship class.
