Application insights not logging Requests,Page views, Custom events

Question

I have promoted my app from dev to stage environment App Service.But now I cant see Page views,Custom events getting logged in my Application Insights which was logging fine in Dev.

Why is this happening?

Note:
1.I am using correct Instrumentation Key

2.Track calls are 200

3.The app is a Teams tab app built using React and using React plugin for App insights(working fine in dev)

4.Runtime Stack for dev environment was Node.Js but for Stage is .NET (Is this causing this issue?)

Please help as I am stuck for a long time.
Let me know if u need more info.

Also Note I have gone through all scenarios in Troubleshooting guide
