Note field not available on Quick create (Account/Contact)

Hi all,

Since today I've noticed I don't see the note field on the quick/creaqte view on Account/Contact level.

I tried to add the field but when I'm in adaption mode/edit screen (silverlight) I could not find the note field in the Additional Field List.

When I click on a certain customer I see the note field is available on my screen:

I'm neither able to add the note field in Silverlight nor in HTML5 (in the quick create view)

I also test this issue on our other tenants and I have the same result.

I tried to hide the field (on edit mode) and tried to add it to the quick create but I still don't see it.

What do I need to do?

Thanks in advance!!
