New iPad, no volume control on doxy

Here is what I’ve done to trouble shoot. I have tried volume controls with other websites (music, youtube) and they work fine. I have tried with Safari and Chrome and doxy has same problem on each. The volume is consistent and low no matter how I move the controls. Interestingly, when a trial session was open but minimized, the volume was loud and controllable.

I have given Doxy almost a one year go of it. They seem unable to get this telemedicine service working without some sort of major glitch. Seriously, if it’s not one thing it’s another. I’m not sure if it’s a funding problem, or what.
