I forgot to answer your question: there are only two pages, but those buttons do toggle me between them.

Everything’s fine with that PDF on my system, using viewers:

1. Acrobat Pro
2. Preview, from MacOS  (has no link previews)
3. Preview from TeXshop (with link previews)

Also worth testing is to zoom the window to ~300% and check all your links.
Otherwise, in full page views, some links may seem to be doing nothing
as the current view is already showing where it links to.

First, when I have just typeset/compiled the pdf (and not done anything with it yet) I can, as I used to, click on the hyperlinked reference, and I jump to the appropriate page.  Once I have done that (just once) what I get the next time I try to click on a link is precisely what your screenshot shows.  The tool is elusive, but even if I do catch it, I can no longer automatically jump to the appropriate new page.  I tried this yet again (that is, I re-typeset the test file)
and again,I could go to page 2 and then click on one of the items on page 1 which are linked, and (even without seeing a preview box) the view jumps to page 1.  Once that has happened, though, it never happens again.  Every subsequent time if I either click or hover over the linked item, I get the preview box, and (I think in either case, but certainly if I click on a link) I get what you are calling the tool-popup, but I am unable to jump to the appropriate page.

Yes, I understood you to be saying this earlier; nevertheless it is good to be able to eliminate other possibilities.
It is a very strange behaviour.
Do you get any changed behaviour if you use the little “back view” arrows to return to page 1 or page 2,
after using the PDF’s hyper-links? That is, the left-facing black triangle in this image:

What I find strange is that I DO get the desired behavior on first try, but (absolutely consistently) not again, unless I re-typeset, in which case I get my first chance to jump, but never again until the next re-typeset. Quitting Texshop and coming back to it also doesn’t help.

Can you send a 2-page document, as a PDF.
I don’t believe that there’s anything wrong within the PDF, and it’s somehow all just on your own system.
But as usual, let’s eliminate the PDF itself as a possibility.

Howdy,

I've discovered something relevant to this hyperlink problem.

I have had the Mouse Mode in the Toolbar of the Preview Window default to the Small Magnifying Glass. I noticed quite a while ago that when I typeset a document and TeXShop opened up the Preview Window the Mouse Mode wasn't initialized properly; e.g., clicking in the window wouldn't open the Small Magnfying Glass. At some point recently I opened up the Help->TeXShop Tips and Tricks document and was surprised that the Mouse Mode was initialized in that case and hyperlinks didn't work at all! However, if I selected the Text, Hand or Selection mode hyperlinks worked perfectly. Once I set the default Mouse Mode to Text mode I have had no problem at all with hyperlinks. The combination of initially being in some unknown initial mode and having the default being one of the Magnifying Glasses is what was giving the strange sometimes working and later failing problem.

So the solution for the problem is to make the default Mouse Mode found on the Preview tab of TeXShop->Preferences to Text (or Hand or Selection) mode.

I've reported the problem to Dick Koch and the next update to TeXShop will fix  the initialization problem but it will still be necessary to set the Mouse Mode (either by the default setting or by clicking it in the Toolbar) to Text, Hand or Selection mode. Also, I wouldn't expect an update to TeXShop until Big Sur (macOS 11.0) comes out.

Good Luck,
