If an iframe in Promolayer's HTML content block is not working as expected, follow the steps below.
Quick checks
Does the content work when you open its source URL directly in a browser?
Step-by-step diagnosis
Step 1: Open the source URL directly
Copy the src URL from your iframe tag and open it directly in a browser. Check whether it works as expected.
If it works when opened directly
The issue is caused by iframe behavior, such as cross-origin restrictions. This is outside the scope of Promolayer. Please check the implementation of the embedded content, or contact the provider of the service you are embedding.
If it does not work when opened directly
The issue is with the content itself, not with Promolayer. Please review the implementation, or check with the content provider.
