Two app tabs reference to same spreadsheet - allow editing

[Jeff_Hager]

Duplicating tabs is fine if you just a different way to view it, but since detail layouts are tied to sheets. Any changes from one tab will affect others tabs that use the same sheet. I would create a duplicate sheet that is used for view only on your second tab.

FInstagram Profiles (Bug?)

I’ve updated the FInstagram sample to use the new Relation columns in the Data Editor. You can make a read-only copy of the user profiles by mirroring the Profile sheet in another tab, but this is a bit too advanced to include in the template. Create a second tab in your sheet and put in cell A1: ={Profile!A:Z} to create a copy of the profile sheet. Now use this as the read-only profiles in the app that cannot be edited.
