Our Features Services all have related data tables to store information from Survey 123 forms. Every service has a number of views layers in order to restrict data/editing capabilities between users.
An example of our services is as below:

However, now when we create new Views from any service on our system - the tables do not appear.

When inspecting the layers from Settings > Update View it seems as though the tables are included

As it is across all our services rather than just in one, I suspect maybe this is a bug?
