I love the Lollipop update on my Sprint HK Edition M8. This is the only small bug I've found so far. When entering an area of roaming, I get a warning message. I don't have roaming guards checked. Very small bug and just curious if anyone else has this problem?
Try switching network mode from Automatic to LTE/CDMA and see if the message disappears. Automatic includes GSM roaming and you have GSM roaming guards enabled.
