Getting blank screen on iPhone on clicking Microsoft oauth 2.0 button in PWA web app

Hi There,

We are facing signing-in issue using Microsoft oauth2.0 in pwa app. we have configured the details and pwa app signing using AD credentials works fine on browser safari. but when pwabuild app is installed on phone it gives blank screen on phone when click on sign in button and it stuck there and nothing showsup after that.

Please help me solve this issue. I am using below URL for sending the http request from the app-

https://login.microsoftonline.com/<tenent_id>/oauth2/token?grant_type=urn:ietf:params:oauth:grant-type:device_code&client_id=<client_id>&device_code=<device_code>
