I am not going to upgrade to 3.1.24, it is too much work to make all the changes to the ticket and all the other changes needed in our busy season. If I upgrade it will be when 3.2 is available. It would be nice if someone tested to see if the iPhone app works with older versions of EE! If I download the app to test I do not know if I can re-install the old version back on the iPhone if it fails.
There should be a note on the iPhone update on compatibility for users who don’t frequent the forums, as they might just simply download the app.
