I’ve just created a new collection and started adding few products. In a second time I was adding additional products to it and the collection disappeared from the list. Already tried to re-add it with same name, but it says “Already exist”. So, why it is hidden from my account?
That happened to me last weekend. My collection did not appear in the store I created it in. I had to go to my profile page, that had all my store collections and I found it there. Since there were no products in it, I deleted it and then I was able to create a new collection, using the name I had just deleted. After creating the collection again, I had no problems finding it under the correct store.
I found it under my profile name, that had all my collections, from my 3 stores.
Maybe I just needed to review better new changes on Zazzle collections. Under my Zazzle Member (Not Store) account I can see the collection right now and I’m allowed to manage it.
