I have a couple devices running on iOS 9 as that's our minimum supported version.
After I receive the firebase distribution email, and tapping on the download link, I got redirected to a blank web page in these devices.
The same provisioning configuration works OK with other devices, except these two. I verified that UDIDs are included in the Provisioning Profile with a valid Certificate.
Can anyone point out if there's any issues with iOS 9 and Firebase adhoc distribution?
