I'm having trouble uploading the app to App Store Connect because I'm supposedly using UIWebView and haven't been using it for a long time if it's not WKWebView as I had this problem before. I find it strange that since I installed the B4i 7.80 Beta version it threw this problem even with all my iOS apps.
I have even tried it with an application that updated without problems 3 days ago and I have the same results that I did not have before.
There is indeed a reference to UIWebView in the IPA you sent me. You can see it by finding the binary file inside the IPA package. Extract it and then run (on the Mac):
B4X:
nm Vango |grep UIWebView
It will return a single line. If it doesn't return anything then there are no references.
Next step is to check all libraries. You can run this command inside the Libs folder:
