Hey , How did it go?

I am using Catalina and followed the re-signing instructions successfully. After re-signing with DER entitlements I was able to launch the app in my ios 15 device and use it. But I noticed one weird behavior in regards to the App launching icon. The app Launch icon appears as white icon with lines in it, when I tap on the icon it launches the app and for a short while (before app opens) I can see the proper Launch icon for the app. If I close the app and go back to Home screen then I see the proper Launch icon for a second or so, then it goes back to the white icon. Is this indicating an issue with signature or something else? Follows the white icon.
