I have been using font MillerBanner but it has now disappeared from adobe site.
Please advise, thank you.
If your font family was offered from either the Font Bureau or the Carter & Cone font foundaries, it is no longer available through Adobe Fonts because those two foundaries decided to pull all of their fonts from Adobe Fonts. You will need to contact the owning font foundary to license them directly, or you can search through Adobe fonts for a similar font.
Dov Isaacs posted an explanation here:
I am really upset that you have let me down, and that you have not even notified me of this change.
As I understand it, Adobe did notify users of the fonts from those foundaries that they were being "retired". Unfortunately, that's a term that's subject to misinterpretation.
In any case, it's not fair to blame Adobe for "letting you down". Removal of those fonts was a decision made by the owning foundary, not by Adobe.
[Also note, I am not an Adobe employee nor an employee of either font foundary, so don't blame me either. :-)]
