I have a problem with the icons ... both with the simulator and with the creation of .ipa Ad Hoc it doesn't show the app icon.
The dimensions are correct and I have also tried to reduce by one pixel but nothing ... it always shows me the PubCoder icon.
I'm using version 3 on iMac High Sierra. I've tried both .png and .jpg.
With the previous version I did not have this problem.
I'm going to publish the app but I can't do it because of this problem!
