I have started to get reports from users that have updated to IOS 8 that the file upload field renderer stops working before any file can be selected (just after choosing camera och library). I've found some bug reports on the first IOS 8 versions and Safari doing file uploads from the browser. So I have asked the users to make sure they are on IOS 8.0.2 and try both Safari and Chrome. No feedback from them yet but I wanted to check if there are any known problems in this area. Will update on of our devices later today to do some testing.
