It's there a documentation to get the difference between Legacy mode vs "normal mode" load with turbo form in Microsoft Dynamics CRM Online 2016.
We actually have some probleme with that and i need to find a source about that.
example.
With IE when legacy are activate, form load are very slow, if not, the process flow are "flicker" with optionset control in the process flow bar
With Crhome, if the Legacy mode is activated, i need to press tab one time to change the focus on each control, when is activated i need to press tab two time.
I could probably write some code to "patch" those comportement, but it's there another way ?
