Online Player unresponsive

Hello there,

I am a using the Online Player with my D&D 5E group.

The problem I have is that an hour or so into our game the UI in Edge starts becoming unresponsive. I cannot start/stop an element and selecting a different mood is lagging really hard. This becomes a frustration and is distracting me from DMing, as I need to start troubleshooting.

Is there any way to work around this?

Thanks!
