Following up here: Thank you for your patience! I've confirmed that Brandfolder is still the correct tool to use for product images and assets. However, there is a known issue with the automations that give partners access to images. The team is aware and working on a fix.
In the meantime, are there specific product images I can try to track down for you? I might be able to provide them directly. (No promises there, but I'll do my best!)
