NRF52 BLE NFC Paring Example not working

Hello,

I've tried to compile the experimental_ble_app_hrs_pairing_nfc example. The example requires the NordicSemiconductor::nRF_DeviceFamilyPack version 8.3.1. There is an issue when I try to download the package as shown below:

It seems that the package is no longer available. Does somebody has had a similar issue?

Additionally I have noticed that many of the Nordic packages are labeld "alpha" (see below). Are the packages ready for production use?

Best,

Valentin
