Bundles are rebuilt when images are added/updated/removed.
On the uploads screen in our back-end, you can see what’s the status of a bundle. When a bundle is pending this’ll be indicated there. If it has already been built you’ll be able to download it.
At the moment, it’s not possible to manually request the build of a bundle.
On the client side, bundles are available for download if the order is closed or all models have been approved.
There’s a exception when order is suspended which won’t allow bundle downloads at all.
