A blank page displays on opening the android app

I have an app on playstore which is created in ionic 2.

App was working fine till I updated the OS to 8.1(Oreo) of my Pixel XL device.
After that whenever I open the app it displays the blank screen.
I tried uninstalling and reinstalling the same version from playstore.
But things didn’t work.

Can any one suggest whats happening. And whats the best way to clean out the earlier storage or cache on application installation


Try to run the app with debug inspector and check if you have some errors
