InDesign 2020 not tagging lists properly on export to Interactive PDF
If a paragraph style is used to define a tag for export to PDF, all numbered and bulleted lists used with that style inherit the same tag, rather than the list tag <L>, <LI>, etc.
Please use a separate style for the bullets with tag set to [Automatic]
You are experiencing the issue due to an accessibility related bug fix done in v15.0
Issue fixed: List should not export as List Tag if another tag is assigned
Please let us know in comments section if it is otherwise.
Yes, I have updated to 15.0.1. It fixed some issues but not this one.
