Hey!
Have same problems and yes, something weird happened after I built the app with expo for iOS standalone ipa too…
I rebuild app, change icon name, looking in package content, change app version…but still have problem with ios icon! i wrote to the support team and waiting for an answer…but still no one answer me
But it’s not! May be i doing something wrong? in IDE i just make exp build:ios, than download ipa and deliver it to application loader. Nothing changes…
