How to edit the font, style, size or color in Acrobat Reader DC?

[treedesign]

I created a fillable PDF form in Acrobat Pro. I would like my customers to be able to edit the font, style, size or color in Acrobat Reader DC.

When I test it in Acrobat Reader DC, [Command + E] on a Mac / [Command + E] on a pc is supposed to pull up the "Form Field Text Properties" box, but it's not happening. It's shows this box:

Am I doing something wrong? Is there another way to pull up this box below?

Do you allow rich text in the form text fields?

In Acrobat, go to Form Edit mode, right-click the field(s) and select Properties, go to the Options tab and tick the "Rich Text Formatting" box.
