@johnmac22911, Not sure if you turn your phone off after updates or even every few weeks to let it reset. But, it's a good practice to do so.
The first thing I recommend doing is shutting off your phone for 5 minutes. Then turn it back on and try and send a text message. See if it sends it from your phone number. Sometimes doing this simple reset can fix the issue.
This next thing might seem obvious, but I have to ask. Is your phone using a cellular network? (Sometimes folks use their phone on WiFi only). If it's on a cellular network, then I would go back into the ***Settings*** > ***Messages*** > ***Send & Receive*** > ***Click on the Addresses*** and double check that the, ***Start New Conversation From*** box with your phone number is the one that is checked.
If there is a check mark next to your email, then uncheck it. Then click out of messages to go back to settings. Then try sending a text message to test if the settings work.
