Observed Behavior:

Zoho Sheet View ignores any Territory you've chosen, and exports All Opportunities visible for the selected View, such as All Opportunities, or My Opportunities.

Expected Behavior:

I would think that Zoho Sheet View should only export Opportunities that are visible for BOTH the selected Territory and the selected View, which I would call the Intersection of the selected Territory and the selected View.

This behavior also occurs in Contacts, but I didn't check Accounts or Leads
