Data usage - many MBs for a few location updates

A phone leaves the house for about an hour. In this time about 10 location updates are happening. Afterwards, 8-20MB of data is used. Seems like every location update takes about 1MB. Even stranger, the direction of the data from the home network to the phone is 20x higher than opposite.

No cameras/streams/floorplan enabled in HA.

Does someone have an explanation? What is happening?

Anyone with an idea?

It is still a problem and seems an empty Lovelace YAML does not make a difference.

Still happening…
