poster image is set for custom thumbnail in scene7 player config, and we are able to see the expected thumbnail for a while on page refresh, but after some time this custom thumbnail is not visible on the video, how to resolve this problem.
Can you confirm if the path set in the posterimage property is resolved with respect to serverurl property.
Also, can you try giving hardcoded image path directly and observe the behavior.
Thanks for sharing the URL to check. It works fine for me, tried in Chrome and Firefox.
Couple of things to check
if we inspect the page, a network call goes automatically which cause removing of posterimage below is the screenshot.
