Launch Screen and app Icon still the olds after setting new ones

Hi,

We have an iOS app currently running in Appstore and we have decided that the time has come to change the logo app and our launch screen. Seems to be a trivial task - get new images, substitute old ones with the new ones, build it and ship it. What could possibly go wrong?


Surprise! Launch the app - an old image is looking at you from the screen of your Apple device... No matter what I have tried to do in code - the image didn't want to change to a new one.

-Delete old images add new images with new names.

-Delete old launchScreen.storyboard add new launch screen with new name.


For the logo icon the older one appear for a while before the new one on ios 13.2 and the only solution is to delete the application and reboot the device but this solution is affecting our end users and there data.
