iMessages deleted from iPhone are not being deleted from MacBook Air Messages App, and vice versa
I generally access my iMessages on my iPhone, and if necessary, delete those that are either spam, or no longer applicable or wanted.
To my surprise, this action is not being replicated in my MacBook Air Messages App, where I not only need to "re-delete" them, but I'm also unable to identify them as spam where applicable when I do. Most inconvenient.
I'm sure there's a simple resolution to this one, but I've not been able to find it here in the Communities. I hope therefore, that a kindly and knowledgeable participant may be able to shed some light on this one for me.
