I am attempting to use the QR code to install my app on an iPhone 7+ with iOS 10 but it only downloads half way and then stops with a "Cannot install at this time, please try again later" error message. It works on other apple phones as well as android phones. Does anyone have a solution?
Edit: I was able to load it on an iphone 7 that was running iOS 10, iPhone 7+ is still a problem.
Your device's identifier must be part of the provisioning profile; if it isn't, the app will fail to install.
Also, make sure that you aren't using a wildcard for signing; those aren't supported anymore.
In the quick suggestions
Make sure you have an enough space on device, if not then remove some data or media file from photos app.
Check WiFi connection on iPhone 7
Doesn’t help anything check Apple server down status for you.
Thanks, i will update you soon if i found in future.
