So, how has beta 4 been performing for everyone so far, now that we (those who upgraded yesterday) had another day to use it?
Based on some replies in a new thread at https://forums.macrumors.com/threads/1616305/ hasn't gotten that many replies about this so far, but the one or two that's there (for now) seem to suggest that the issue was likely addresed in beta 4.
On my part, it seems that I haven't been missing any calls as far as I can tell, which is good.
Mine was perfect since Monday, but I did have a random call go to my voicemail with no missed call notification last night. Not sure what the deal was.
