Have you tried removing the format menu in custom menus.
I tried to remove the Format and Style menus but it appears that those are locked and can not be deleted. Unless I'm missing something.
I created a blank custom menu and when I clicked on a field all the popup menus disappeared except that Style menu.
So my solution has a standardized design on IOS but the user can write with a 72pt font in RED whenever and wherever he wants ? Really ?
Granted, very few users would do that but still, there must be a way to eliminate the possibility.
You could use an auto enter calc to remove formatting.
You mean in one of the field's triggers ? I thought of that but it's quite a pain to that on all my fields in all my layouts .
I really would like the menu to disappear.
There should be a way to do that.
