Hi,

I noticed in TTN mapper that the shown measurement points are dependent from the zoom level.

I few days ago I did some measurements around my gateway and was disappointed that still the old measurements were visible.  
Then I noticed that zooming **out** suddenly brings the new measurements on the map. Zooming **in** brings the old measurements back.

Today I added a measurement. It is already visible, but only if I zoom **in** quite far in. Otherwise it is not visible. But the measurements from a few days ago are now visible in all zoom levels.

Is that kind of a bug or a glitch while new data is still processed or is there an intention behind it?

Thanks.

Caching. You’re just seeing cached tiles. Wait a couple of days and the old tiles will be regenerated.
