What is mean Map badge

Hi,
What is mean Badge show on Map menu, Is it data not update?
It shows up very often.

has to do with the socket
<Badge color="error" variant="dot" overlap="circular" invisible={socket !== false}>

It means you have a problem with WebSocket connection.

Thank you, How can we fix this problem or not? or where point to check it.

First check network console to see what the actual error is.

Mostly we will found this issue on mobile app traccar manager, but on desktop we will not encounter this issue.

Does it happen in a mobile browser? If yes, you can still check network console.

thank you Anton, we will try to check as you suggest.
