iOS notifications for messages read on another device
I have an iPhone 6 with iOS 11.4, a MacBook Pro w/ Touchbar running High Sierra 10.13.5, and an iPad Pro with iOS 11.4. all synced with the same iCloud account.
When I receive a new message in the Messages app, if I read it on my MacBook Pro or iPad, I'll still get notifications for the new message on my iPhone up to hours later. This doesn't occur with my iPad or MacBook Pro if I read the new message(s) first on my iPhone.
I've tried restarting all my devices, disabling and re-enabling notifications for messages on all devices, changing the notification type (banner vs sound vs preview), removing my iCloud account and re-adding, etc.
It gets a bit annoying to have a new notification for each message received hours earlier. Is there any fix for this?
