@wardred ,
the link is working now, thanks!
The selection is actually working (which you can see if you switch to Edit Mode after selecting a Face, or even select linked), but you don’t get any visual clues that it is working, so pretty useless this way. This suggests, however that it is an Overlays problem…but also, the Texture Slots are greyed out…don’t know why, doesn’t appear to have any consequences for paint abillity…
I highly suspect it’s a bug…there has been some work done on Texture Painting (mostly ‘internal workings’), so that’s totally possible.
Will do some more tests later (a bit busy at the moment), and maybe repeat the problem in a simpler file, so it can be reported as a bug (if I don’t find some setting that needs to be changed, or so).
