Apps are not installing at the time of enrollment

Hi People,

I am new in enrollment of the android devices. 

I have a few devices which I need to enroll as Corporate-owned, fully managed user device. 

In order to do so, I completed the steps below:

1. Scan the code

2. Login as company credentials.

3. Setup the pin number.

After that I am stuck at installing the apps.

As Microsoft Authenticator and Microsoft Intune are required apps, without that I can't do anything. 

Installation of that apps are just going for ever. 

Please see the screenshot  and help me if you can .Thanks
