I have two volunteers using iPhones with ArcGIS collector, but cannot get Collector installed on one of them.
iPhone 5 running 6.1.2 installs fine however, the other, an iPhone 5 running iOS 6.1.3. does not install.
Obviously I may have to get them to upgrade their OS as the message says but I am curious to know why this would be happening.
Is there something that has changed with Collector recently or any suggestions to get collector working with iOS 6?
