We had a cache plugin but I deactivated it before the demo import (all of the third-party plugins were deactivated, so we had a clean WP installation)
the problem is not with the import itself – it’s marked as completed, the problem is that it’s completed incorrectly and all of the styles are missing.
I have installed the theme and have the same issue with the homepage slider images not showing at all. Also, all of the styles for font’s blocks are missing as well.
I’ve already upgraded the memory from 256mb to 1024mb but that doesn’t seem to help.
