Screenshare requests not showing up
Hi, my friend and I often screen share using iMessage but lately the requests haven't been coming through. I will ask to share her screen and, while the screen sharing app opens and it says it's waiting for her to respond, she does not receive any pop-up that lets her accept. Same goes when she invites me to share her screen. This was working fine until a few days ago, then it started taking a few tries to get the pop-up and now it seems that it isn't showing up at all.
Does anyone have any suggestions? We've tried quitting messages, rebooting the computers etc. but nothing seems to work. I have a 2015 MacBook Air and she got her MacBook Air late 2018. We are both running Mojave.
Thanks!
