My expectation is that when I sync a Printful store, products should come in with images if there is an image field to capture them.
In the related Product Type Variation in addition to adding attributes of size and color (which information comes in fine) I have created different types of image fields using the file->image field and then also using an entity reference field for the media module. In both cases I named my field 'image'. When I go to sync the products, the other information comes in great but no images. Is there a trick? This might be a documentation issue. I am seeing some whispers in the different issues about clearing caches or removing (unsynching) the store, and have tried clearing the caches but have heard that clearing the store connection (unsyncing) might also clear the products from my Printful store.
Incidentally, I have also contacted Printful to see if the issue is on their end and will report back. Their mechanism for creating/downloading images seems to timeout as well so it could be an issue with their servers.
