I just spent over 45 minutes on a call with support. I had to open a new support call, uploaded a description of the problem (yet again, typed it all out) and then the support guy couldn't find it and I had to go through the story again on the phone. They also didn't see all of the screenshots I uploaded. Whatever.
After 45 minutes, he "sent it to the developers" they replied that it is obviously on my end and their only solution was to reboot my router. Dear god, like I hadn't done that now dozens of times.
I've had new cables installed to my site, I have a brand new modem. I have new connectors. I've reinstalled the app.
I use PingPlotter and during a call this morning there was literally NO latency nor packet loss anywhere during an entire call, yet after 20 minutes the voice lag was 5-8 seconds, yes 8 seconds!, between when I spoke and they heard me. Grasshopper isn't capable of resolving this for all of us. Time to move on and find someone new.
