I've had a search through previous issues and can't see this so hopefully you'll be able to help me.
I'm trying to install an app from my App Manager account on an iPhone and I'm getting the "can't be installed at this time" issue. This occurs if I download it though App Manager or directly via url / QR code.
However, if I download the signed app on a mac I can install the app through Xcode with no issues.
The UDID is definitely in the provisioning profile. I was able to install via App Manager yesterday, but I did try to add more devices to the profile this morning (after which I resigned the app using the new profile downloaded from the Apple developer portal). Since then, I have been unable to install any version on that iPhone or the others that I added to the profile.
Have I missed something?
