Adobe will end support for authoring with PostScript Type 1 fonts by January 2023. This FAQ article details the changes and what they mean for your projects.
The Adobe Fonts service will not be affected by this change. Fonts activated from Adobe Fonts will continue to be supported everywhere you use them now. Any OpenType or TrueType fonts you have installed on your machine will continue to be supported as well. Note that operating systems are currently moving towards supporting the more robust technical possibilities of OpenType format fonts, and ending support for the Type 1 format. Most browsers and mobile operating systems currently do not support Type 1 fonts.
