Email being deleted from multiple accounts
My wife and I have 3 gmail accounts that we have synced on our 4 Apple devices, 2 iphones and 2 iPads. We have been using the Mail app for years with no problems. After a recent update, emails are now being opened and or deleted in multiple accounts. For example, if we receive an email from a sender that is sent to both my email and my wife's, if either of us opens the email, it will also show as read in the others email. Same if I delete an email in my account, it will delete from my wife's. This has caused us both not to see some important emails. This has caused us to have to use a third party app until we can figure out how to resolve this problem.
