I am testing PDF link functionality in iPhone and Android devices, in particular links that span more than one line and have multiple OBJR annotations versus links that have only one OBJR annotation.
On a desktops/laptops computers, when PDFs are opened in Acrobat Reader, and users who can’t use the mouse use keyboard to navigate the links, multiple OBJR annotations causes extra tabbing. So, I usually make sure the Links have only one OBJR .

These are my questions:
Thanks in advance, Rosana.

Guidance and Research
While specific studies focused on OBJR annotations may be limited, general accessibility principles apply:
In summary, using a single OBJR annotation for links is likely to improve the experience of sighted users on mobile devices or browsers. For more comprehensive insights, consider investigating user feedback and accessibility testing specific to your audience.
Hope this helps.
