It does look like the same issue, but I’d also noted in my initial post that the “top identifiers of [Observation Taxon]” section on observation pages isn’t working for me, being perpetually stuck on loading. (I didn’t think to make a separate report for that, since it seemed to me like another manifestation of the same problem.)
Is that best considered a separate issue? If so, is there an existing bug report for that, and if not, should I start one?
