Dashboards (with Shared Formula) breaking while migrating from Dev to Prod

Hi DRay , 

Thanks for the response. Few clarifications - 

• We have added 100+ shared formula in EC. And its there for Prod as well as Dev EC. And the EC ID is same. 
  • These shared formulas are getting used in 1 or more dashboards and are working fine in both Prod & Dev
• Updating the Widget / Dashboard (in Dev) - Now, if I am adding an existing shared formula in the widget then it is working fine for Dev. 
• Migrating the updated dashboard (in Prod) - While migrating this change to Prod, the updated widget in the dashboard is breaking (even though the shared formula exist in Prod EC as well). 

To your points - 

1. Yes, the widget was working before and not its not in Prod (after migration)
2. Widgets in Prod & Dev are using the existing shared formulas. No new shared formula is getting used here. So technically no change is required for EC. 
   1. And EC gets refreshed every 4 hours, so that is also not fixing the widget issue. 

Hope I was able to give the context. Looking forward for the solution. 

Thanks!
