Cell Phones on Wi-Fi not connected...

[LWHSymphony]

We have staff members that use the Zoom app on their cell phones as their work phones and are connected to our 1 gig Wi-Fi. They are receiving calls but then the app will not connect, and they receive a message "Not connected. Attempting to reconnect..." This is causing a lot of frustrations for our constituents and staff. This is not the same experience on our hard phones or computer app, but the whole company is mixed on how they use Zoom. Anyone else experiencing this?
