Tbh it’s probably less of an Adobe problem and more due to the absolute mess that is PDF annotations.
Despite being a defined open standard, most free PDF viewers either don’t support them (zathura etc), or fuck them up (GNOME evince). Even some of the viewers that do support them like Okular need extra configuration.
Unironically Firefox as a PDF viewer actually has the best support for PDF annotations.
