Hi Everyone..
After updating from app store shows blank white screen in iOS 12.1 but after deleting and reinstalling the app from app store works fine.
As I cannot share the code, logic implemented in App Delegate includes :
1) On first time, app waits for 3sec to get the device token n store it locally into device. Using the same device token as query string is passed to UIWebView to loadUrl.
2) On second time, app checks for the fresh device token n matches with the existing token. If same, then saved device token is send as query string to UIWebView else new device token is replaced n send to UIWebView to loadUrl.
Why So please suggest as on all other versions app running fine.
