message on my Apple devices of weak security but iPad and iPhone don't seem to recognize a change

I recieved a message on my Apple devices of weak security and asked me to reconfigure my router. I did so, but iPad and iPhone don't seem to recognize the change and still send the weak security message and use my old WPA setting in that message. So, I don't believe my devices are acknowledging the change I made in router from "WPA - WPA2 Personal" that i changed to just WPA2 Personal. ( I dropped the plain WPA). Router gave me no other options. Did not see an option to add AES to it. My iPhone, however, still says I am at the previous WPA setting (which they also call TKIP).

I did "forget" my network and then sign back in again, but that makes no difference.

I also tried shutting off my iPad but the weak security message remains. iPhone 7, up to date. Also iPad.
