sonaar Yes, pretty odd too, Could not find out which device this should be.
Well, I guess this one which is not active at the moment I guess 😅 Check your license on the RN Account - one is currently deactivated.
The only thing that I can imagine that could impact UID is HDD hot swapping or wrong aggregation of drives - for eg. USB drive went as the primary one - though there's already a safety check for such scenarios 😒
If you have still concerns please send me emails with your current UID's and we'll find out what's going on.
