Widget "No data available"

My project is to get lat-lon data from Lora devices but one of my device not cannot recieve and show the data.

which device are you using? it has a map widget on the dashboard.

The widget now plots only the latest location.

Last week it can display device location history.

?

B-L072Z-LRWAN1, I name it LoRa2 in Dashboard.

can you try removing the widget and let it re-add on the next uplink (you will lose all your history)
