Hello,
I see that you are using jestor. According to their documentation, the Stable URLs do not change. There should not be any issue using the stable URLs with Adobe target for testing experiences. Refer to the Activity URL documentation: Activity URL
If you are attempting to set up one activity on multiple pages, this is possible using your stable URLs by adding additional pages within the activity. Check out the Multipage documentation: Multipage Activity
I hope this helps!
Matt
