Zoom says a group call at 1080p will take 3Mbps. The GPs connection should, theoretically, be able to handle 30ish simultaneous calls. Connection issues at home is probably a Wifi issue. They might have a poor signal to the router. Devices on the same channel will interfere with each other. As will the neighbors' network. And these days there are a lot of networks out there that interfere with each other. The other option is that the shared line back to the ISP can't handle the traffic. That's something that definitely can be happening due to covid. Traffic patterns are quite different and it's possible that things are getting saturated. But it's probably the wifi.
