Please find the attached pdf. Link present in it shows tooltip as "generate hotspot" in adobe reader and shows proper link in adobe acrobat pro
Please share your findings.
This is a weird one. The Link annotations in this file contain a "Contents" key which is used by some annotation types to display a caption when the user hovers above the item, but not for Links. So Acrobat should be ignoring it, I believe, but it seems it doesn't and displays it instead of the actual URL.
This is something you need to solve in the application that generates these files, though. I don't believe you will be able to do it in Acrobat itself, nor would you be able to change how it behaves.
