Hello,

I encounter a serious issue with InDesign 2020 (15.0.3) when renaming hyperlinks shared destinations (linking pages in the same document):

Those links seem still working in InDesign when clicking a page icon in the Hyperlinks panel (it leads to the proper destination page)
They don't work anymore after the PDF export in Acrobat (the links are clickable but they lead nowhere)
I had to re-create all the shared destination links in the document, which is a huge waste of time at least and makes the feature very unreliable.

I made 2 tests files, here's the Dropbox link: https://www.dropbox.com/sh/lugt070lkyzvnwr/AABIqY90wl4A0ujhD66K6nFaa?dl=0

Test A

A 3 pages InDesign file (and the related exported PDF).
3 shared destinations leading to each page, named Page 1, Page 2, Page 3.
3 links on each page, set using the shared destinations.
All works fine in this file once exported as interactive PDF.

Test B

Same file as Test A except i renamed these shared destinations:
Page 1 > Page 1-Renamed
Page 2 > Page 2-Renamed
The links using these shared destinations don't work anymore once exported as interactive PDF.

And here's my post in the community forum:
