Custom notification with HTML

Summary:

Content (required):

Hello everybody,

we are customizing a custom notification containing an attachment inside it.

In particular, we have inserted and created everything we needed inside the data model.

Within the bursting of this notification, precisely within parameter 5 of the bursting, we have inserted the attached html code for displaying the body with the inserted content.

By scheduling this notification, we correctly display the entire body inserted in this parameter but it does not appear to be responsive on certain devices such as mobile phones.

Do you happen to have some information you could give us to make the displayed body content scale the same for both devices.
