First of all thank you for the import tool and congratulations for the work.

On the other hand, perhaps it has already been mentioned, but while importing and having checked that all the photos were in the IG backup, I realized that after a certain point Pixelfed's import tool did not recognize the latest publications.

Then I found the problem:

The backup of those unrecognized posts is no longer done by IG in jpg but in webp.
