Spectrum tv app..no audio

Since the last Apple and Spectrum upgrades I get no audio with Spectrum TV app on iPad mini. Netflix and Amazon Prime Video work fine. After 3 hours on the phone with Spectrum I was told there is a conflict between the operating system and Spectrum. Personally, I believe it is an engineering issue on Spectrum's part. Is anyone else having this problem and has anyone found a solution? It works on my iMac and iPhone, but not the iPad mini.

Thanks
