No sincroniza algunos links

hola, tengo un problema con algunas canciones ,antes las habia agregado y las podia reproducir sin problemas ahora me sale " This website is in no way associated with Watch2Gether. Please decide for yourself whether you would like to open it."

This happens when a video can not be embedded in other sites or is age restricted by Youtube. In both cases the videos can only be played through W2gSync.
