Hello. I'm trying to add and remove contacts on my 'do not disturb' list and it always crashes once I choose contacts that I want to add to the exception list. I sent a report to MIUI Threw the message that I get when the app crashed. Also, I noticed that when Assigning a ringtone to a specific contact, it rings the normall ringtone instead of the specific one I asked for. Why is that? Help Please. Josef.
