Umingle Global Matching Problem

I have been using the Umingle random video chat service regularly, but since this morning the matching system has stopped working as it used to. Previously, the application was matching me with people globally and also according to the interests or match topics I selected. Now it only connects me to users from 3–4 countries and the interest-based matching feature does not work at all, even when I choose specific topics. The features I am complaining about were completely free, so I have not made any purchases or subscriptions for them, but I still expect the service to function properly as before. I kindly request that the global matching be restored and that the interest-based matching system be fixed so I can again connect with people worldwide according to my selected interests.
