A few things could be causing this:
- Sometimes this is caused by poor network connectivity. Try moving to an area with better network connectivity, or have the people who are lagging move to a spot with a better connection.
- Your room can also be slowed down if you have too many GIFs, images, or videos on the canvas. Try throwing a few in the trash. Then make sure to refresh the tab.
- If you're still having issues, send an email to firstname.lastname@example.org and we'll help you out.
