Are SAT Subject Tests becoming obsolete? Should I still take them?

Just found out my Math 2 test center for November is cancelled, and it will no longer be administering subject tests in the future. So now I’m back to the dilemma. CollegeBoard lists some test centers near me, but my counselor says none of them are administering it.

How do I even find proper test centers now? Do I just have to contact personnel from every single school supposedly hosting them? Or do I contact CollegeBoard? I’m not sure the COVID pandemic will be gone by the time I start applying, so I may continue having trouble finding test centers (especially since I live in a rather secluded area—had to drive a ways into Massachusetts to take the ACT pre-COVID).

And of course, this would all be a waste of time if colleges end up not recommending/requiring SAT2s for the '22 class. My top choice, Yale, isn’t considering them this year and I’m not sure if they will next year too.
