We are having lots of issues with the People Picker in InfoPath browser forms on SharePoint 2013.
IP Form is 2013 and IE 11 view compatiblilty is off Browse Icon works but you can only use it once. It does nothing the second time that you click it.
IP Form is 2010 and IE 11 view compatiblilty is off Browse Icon does nothing
IP Form is 2013 and IE 11 view compatiblilty is on Browse Icon throws JSON is Undefined
IP Form is 2010 and IE 11 view compatiblilty is on Browse Icon does nothing
IP Form is 2007 and IE 11 view compatiblilty is on Browse Icon works just fine
I have spent a couple days googling for fixes but none of them have worked. Is anyone else having issues with SharePoint 2013 and the InfoPath People Picker? Did you find a fix?
