nRF Connect Updated app - Not showing real Advertising data but default as FFFFFFF...

[Joel]

I can see for the same device on Android nRFconnect that the serial number in advertising data can be seen as here -->

The same device at same time on my iphone X with up to date nRF connect app shows FFFFFF...... -->

I am confused as to what is going on. The above two screenshots are from two phones at the same time but I'm using a nRF52DK.

Strangely I have a different custom board with same nRF52840 chip and I can see the data clearly advertised at same time. You can see this device in last pic above with 0xBA9999999995 in advertisement packet. All my devices use standard beacon and not ibeacon.

Please advise.

I must say that programmatically I can still see advertisement data. Just that the nRFConenct app doesn't show it for one of the devices. Strange.
