iMessage Issue

Hey y'all,

I'm having a unique issue with my imessage system that I haven't been able to find a topic on. My imessage works completely on my phone. However, my MacBook Pro (2020) imessage only works partially. I can send imessages to the majority of my friends but there's like 3-4 people where it fails to send. I'm not sure how to fix this? Thanks.
