Imessage messages from others not being sent to me.

I’m on an Iphone 15 pro and I’m on IOS 27 and for about a month and before I updated my phone, messages i receive on Imessage won’t get sent to me fully, I’ll get a notification saying the persons number even if I have a contact name saved for them and the notification just says “Imessage” instead of saying what the message contains and when I open the conversation the message isn’t there and it’s pretty awkward for business related messages. Also I sometimes get my notifications late, instead of “now” with a notification it will send saying “4 mins ago”, 7 mins ago” or something along those lines.
