Looks like #PixelFed Instagram import doesn't work quite yet. I should've waited for a month at least. :)
I only got six (out of 71) random images at random order, three more are blank and there's no way to clear and re-import (the archive is recognised as having already been processed). Broken encoding in non-Latin descriptions is such a minor nuisance at this point. 😆
The good thing is that it has pulled in the last image I posted on Instagram back in 2019. I think I'll just delete the rest.
Using online decoder to decipher the descriptions, I found out that those are not three more blank images, but three failed versions of the images that have been imported.
