Issue with new app

I was just wondering if anyone else is having issues with the Netvue Next app. I have been using it for a few weeks and have just noticed that the sound is distorted and appears to be making pulsing noise. I am getting it on 2 of my wired cameras so it’s not an individual problem. Also I have noticed that it is fine on the normal Netvue App. Am I missing something, is the Netvue Next app designed for just PC’s and not for mobile phones maybe? Any feedback would be great. Thanks.
