Not sure if I'm missing a step here, but having just registered a Creo licence, I still see a Creo Splash screen when launching a standalone on iPhone.
I re-started Creo after registering a licence.
I confirmed Creo appears be be correctly licensed in the Creo > Registration window.
I rebuilt my app for development distribution.
Removed existing unlicensed instance from iPhone.
Installed new ipa to iPhone
Still see Creo splash screen on launch.
