My iphone cannot send imessages to itself after updating 16.1.2

My iphone was running iOS 16 yesterday and could not send imessages to itself. I could send iMessages to anyone else but not to my own cell number. Sometimes i send messages to myself to remind myself of something or to transfer something from my phone to my computer on iMessage. It quit working. I rebooted the phone and it did not fix the problem. I installed 16.1.2 and that did not solve the problem. I rebooted the phone once and it was not solved. I rebooted the phone a second time and sent a single iMessage and it worked. 5 minutes later i sent myself an iMessage and it was an SMS text. 5 minutes later i sent one and it worked. So it is intermittent.

I am having no problem sending imessages to anyone else. Only to myself.
