PR:
https://repository.entgra.net/proprietary/android-agent/pulls/71

The notification which showed the apps that were not in the device is fixed.

The "Per App Network Usage Configuration" did not applied when checking with wifi(Youtube app was able to use even after exceeding data allocation).
upon updating the policy again and republished, it showed the above critical issue(policy revoke and policy bundle failure)
Note: in this case the initial policy apply is working(In here 2 package names of existing apps were used), but when the policy is unpublished and republished, or updating the policy and apply changes to all devices will result in above critical error.

To-do: Need to test this feature with only mobile data and, wifi and mobile data combination.

PR:
https://repository.entgra.net/proprietary/android-agent/pulls/74

Fix added for apps continuosly running in foreground without disabling the WiFi after violating the data limit. Here the continuous monitoring frequency is 5 minutes. There can be a delay of applying the policy when a data limit is passed. But within 5 minutes this should work.

This is working

Closing due to QA accept
