When I open Messages on my iPhone, the app pops up on my Computer - I don't want this.
I'm using an iPhone 11 Pro Max with ios 14.4 and a 2017 MacBook Air with Catalina 10.15.7
Ever since the recent Catalina update, when I open the Messages app on my phone, it also pops up on my MacBook (see bottom left of the dock). I do NOT want this to happen. I'm signed out of Messages on the computer and have turned off all notifications for it, but it's still happening. Help!
MacBook Pro 13″, macOS 10.13
