Mail.app not syncing read and archived messages between iPad and iPhone
I am having an issue with mail not synchronising read and archived messages on the mail.app on iPad and iPhone using iCloud and gmail email accounts
If I receive an email and read it on my iPhone it marks it as read and the badge and lock screen notification goes away, but on my iPad it still shows the badge and lock screen notification until i open mail.app and then it updates and marks as read or archives the message
Is this normal behaviour or should it sync the message as read and archived before i open on another device?
Thanks in advance
