Comment 1 for bug 1883457

Okay… differently worded :

is it normal thumbnails generated by a snap-app ( and therefore stored somewhere under ~/snap/… )
can't be then used by file explorer or pictures viewer ?

It's a regression between same app-as-deb and app-as-snap.

Just because Ubuntu looks for thumbnails only in ~/.cache/thumbnails or ~/.thumbnails
It should also watch inside any folder named thumbnails inside ~/snap
