Voice mail going to another phone
Since recent update to 17.2.1, my iPhone voicemails are going to my partner's phone (on same Apple account) and not appearing on my iPhone. I can see the missed call but no voicemail. This has meant I have missed several important personal and work-related messages. We have shared the same Apple ID for many years for all of the benefits it entails (calendars, photos etc) and never had this issue before. Please advise the fix.
