Last couple of times I seen I missed a call and never heard it ring. I did fix that issue why sound was turned down not sure. I discovered those missed calls did leave voicemail and that notification is not showing up. Came here to investigate and found issues with the software for the phone OnePlus 9 Pro.
For the voicemail: When a voicemail is left there is no notifications showing for voicemail just a missed call. I have tried different things to get notifications to show but nothing has worked and went to the extreme and uninstalled the T-Mobile VVM knowing that I can always reinstall it later. That did not work, and yes restarted the phone several times and used the house phone to leave messages. If I know there is a voicemail I can retrieve and found them calling voicemail or using the VVM, I just want to know there is a message. Read where others have had this issue but could not find a simple way of fixing this issue.
For software update: Question on this is if there is an update and T-Mobile does not provide it as quickly as OnePlus can you download the new update through OnePlus website? I am there and it goes into detail how to download to computer then to phone. Not something I plan to do at this time since I am not having any issues with the software unless it deals with the voicemail. Just reading where others have had issues with a new update that has caused them issues and the update is months older then what is available and thought to ask for future reference.
Only have the phone less than a month and so far everything has been fine for me till I discovered notifications for voicemail not showing.
