What versions of IE are supported, does it have to be compatibility mode?
IE 10 and higher is required. IE9 works with some controls, but some issues will occur. IBM BPM dictates that compatibility mode is required, meaning BPM 8.5.6 will force IE11 to IE 10 compatibility mode… and SPARK works perfectly fine in that scenario.
Other supported browsers are Firefox, Chrome, and Safari for iOS.
