Can you share the formula in R4?
Mine is: =QUERY(indirect("Accounts!$"&P29&"$2:$"&P40&"$101"),"SELECT "&P30&", "&P31&", "&P38&", "&P33&" WHERE "&P40&" <> 'Hide'",-1)
I think you just need to restore the Insights sheet using Tiller Labs add-on. If you previously restored/updated the Accounts sheet then you’d need to restore all downstream sheets after that so that the formulas get back in sync.
Sorry, @blake. The restore process with cascading downstream dependencies isn’t well supported by Google’s API. We are trying to find solutions to make this more seamless… but, for now, as @heather notes, the best solution is just to restore the downstream templates after updating anything upstream (like Accounts).
