I think I do have a similar issue:

$ snap list
Name Version Rev Developer Notes
core 16-2.26.9 2381 canonical -

$ sudo snap remove core
error: cannot remove "core": snap "core" is not removable

$ df
...
/dev/loop1 82432 82432 0 100% /snap/core/2381
...

$ sudo umount /snap/core/2381

$ sudo snap remove core
core removed

Maybe this helps?
