After updating our two iPhones to IOS17, the calling history and voicemails for both phones are showing up on both phones. This has only started since the IOS17 update. Yes, we are sharing the same Apple ID. Yesterday I spent a significant time with Apple Support and they tell me that this cannot be turned off as consumers requested it. I see a lot of reports where consumers hate it. Yes, I can give each phone it's own Apple ID, but then I lose the automatic syncing of both calendar and contacts (which we find very useful). Does anyone have a workaround for this issue. Also, how can I send a formal complaint to Apple.
