I just tried to implement a parser for the native adv. format, but I noticed that the data first 4 bytes seem to be missing. The payload starts with the mac address right away. Firmware version was the latest from this morning.

That is correct

The other 4 byte are the length of the data an the service uuid. These are parsed on ble level

Just take the mac as first byte
