Got it @Bernie_Carter5069, and thanks for clarifying!
Since you're working on an Adobe Express webpage, the Layers panel isn't available for this type of project, so the workaround you used, replacing the images one by one, was unfortunately the available option. You may also see an exclamation mark (!) on an asset if there’s a potential licensing issue, which can help identify problematic assets.
Also, we’re working on a workflow that identifies and flags assets with licensing issues, so you can replace them directly instead of having to troubleshoot each asset individually.
Thanks for bearing with us, while we make Express better!
