Hi there,
this is another chapter of my daily issues with Apple:
Suddenly the update of IPA to AppStore of an formerly running app failed, when using the Transporter.
I usually keep my Transporter open for days and weeks, maybe that causes sometimes an issue.
From my research for this error I found a few possible reasons and solutions in the web, where I've tried to re-boot my VM first.
Solution:
1. Just relaunch Transporter app, or quit and re-enter it again. (not tested, but sound reasonable).
2. Try completely shutting down your device and then turning it back on and trying. (I've tried this one).
3. Check the matching case of the SKU for new apps:
E.g. "com.company.appName" wasn't accepted. If changed to "com.Company.AppName", matching the AppStore entry, it works.
Sometimes solutions can be so easy, but I hardly see the easy one's very often 😥
