#1: Are the new product you added to the collection? Since you want to display a product on the collection page, you need to add it in the Collection Admin.
#2: It will have 2 cases:
1: You saved in one template and checked on another template.
2: After you changed, did you see it show the changes in Customize? If not, it’s possible that your theme code is faulty.
#1: yes, I added my new product to the collection, and I go to edit customize i saw my new product on the homepage, but the “all product page” doesn’t see my new added part, and the product number doesn’t change.
I edit my customize collection page and save it, but after a few seconds still old page comeback, "save "doesn’t work. (view online store home page can see my new product, but collection page/all product page doesn’t show new product)
#2:same as #1, after changing, I saw it show the changes in customize, but after a few seconds old page come back "save "doesn’t work.
I am a novice and don’t know how to add a staff account. We have 2online stores in Shopify, one can be edited/save “customize” and the online store is also updated successfully, but this one cannot save “customize” changes.
I checked one by one, The settings are the same. strangeness
