Text Messages NOT going out.

I own an S22 Ultra. I agreed to participate in the trial run of this new software. Even was fine until I noticed ( this past weekend ) that my text messages aren't reaching their intended viewers. I have two phones. In order to confirm this, I sent a text to my Note 20 Ultra. Never came through. I even reset my "Network Settings." Nothing has worked so far. I'm wondering if anyone here in this forum has had this issue and is there a fix for it. I love everything else about this version of One UI, but I have to have the ability to text. Thank goodness that I actually have two phones. So, anyone had this issue as well?
