It seems that with the update image views for envelopes, dark colored envelopes now show design colors incorrectly. White design elements on colored envelopes have now disappeared completely
I’m sorry to hear that this is still an ongoing issue for you. Can you provide a couple of example links to the envelopes so that we can investigate this further?
It looks like things are in the process of being fixed? Most of the dark color envelopes have had the design restored. It looks like on a few that are still incorrect, it is in the store, but showing up properly in the marketplace
