Disappointing call quality

I have been increasingly disappointed with doxyme. I feel like I can’t get through a single session without the video freezing, or audio breaking up. It is to the point where I don’t feel like my clients can get therapeutic value from our counseling sessions because so much of the time is spent trouble shooting. Particularly this last week, the audio issues were terrible. Nothing has changed on my end. I know I might not have the best internet, and most of my clients are using the platform on their phones, but there has to be a better quality telehealth option. I noticed no improvement going from the free to paid versions. Anything I should try before I give up and look into other platforms?
