Gallery for voting embeded in my webpage and works super slow on phone version

I embeded a photo contest with 37 photos for people to vote and it is not being useful because the embeded page gets white as soon as you try to vote

It is hard to tell what is causing this issue without further information. We've run some tests and we can not reproduce this issue. So it might be related to the embedding site.

Have you added your host to the allowed hosts like explained in in the embedding tutorial?
Please also check this FAQ article: https://pollunit.com/en/questions/30/what-can-i-do-if-pollunit-is-not-shown-on-my-website

If neither of this is working please send the admin link of your contest, the link to the embedding site to support@pollunit.com.
