About the view, I agree. Redbubble has some weird way of displaying and navigating through products. Even, uploading is weird, and I struggle at times. I don’t think there is much we can do about this.
The best way I found to view all combinations was to click on a product and choose, show all products. Screenshot: https://imgur.com/a/AzRRg
I hope this helps!
Yes, it makes more sense. I have changed it, it’s not reflecting the changes yet. In our experience, it usually takes them a day or two to reflect. I will check again to make sure it’s working.
