I have installed this ROM and I was very happy about it, especially about the GPS side (which works much better than the official 8.2 update), until today, when I had the confirm that starting from 8.2 Xiaomi has messed up with the Bluetooth stack of the ROM. With official Global Stable 8.1.4.0, I'm able to keep my phone connected to my car flawlessly; with 8.5.2.0 from Xiaomi.eu (but I had the same issue with the official Global Stable 8.2.2.0, so I think the problem goes deep down into the MIUI kernel) I can't keep the phone profile and music streaming profile turned on at the same time. I need to disconnect the phone profile, otherwise the music plays for 20-25 seconds and then the Bluetooth connection drops (sometimes, causing even a reboot of my car entertainment system). I like very much the original spirit and hardware by Xiaomi, but being a Xiaomi fan is becoming harder and harder these days :-(
