SimilarWorlds is hanging when using Safari on iPhone

We've got some users reporting that SimilarWorlds isn't responding, or not loading completely when using Safari on iPhone.
This appears to be an issue with Safari, and the way to resolve this problem is by clearing browser cache.

You can resolve this by doing the following:

Settings > Safari > Advanced > Website Data > Remove all Website data > Remove Now

Unfortunately, this will log you out from every website, but hopefully this resolves the issue.
