Why did the barcodes disappear from my packing slips?

Hi,

We've had barcode on the packing slip for months, but since this morning, those barcodes are gone. I've used a google barcode font (https://fonts.google.com/specimen/Libre+Barcode+39). Also, when i try to generate a barcode from a url, which  translates to an image, it doesn't work either.

Has there been any update on packing slips from Shopify which blocks these kind of stuff?

Exactly the same issues here too. Was working perfectly, then all of a sudden stopped. Anyone find a solution?
