The DAU drop of Netflix android app, some questions

  1. Is the for a specific region
  2. Was the app update done in due to external android update or new feature was added
  3. Is there some seasonality

After looking into the android app update was the reason now to dig a little deeper

  1. System : Was the android app update across a specific compoment and which library function was updated.
  2. Internal: Was this feature tested in all regions
  3. External : Was also new content added on compteteior and other player

Deeper dive into system level : Can I see the drop-off rate at the different screen before and after the change?

Based on above data : Android app update has performance impact on content load time due to which drop off has increased.

Validate your finding we need to run performance test and load test on content running and new content load time. Recommend solutions would be A/B new version in region and performance improvement with engineering team on prioirty
