Logitech combo touch keyboard not working with iPad 11 inch pro 3rd generation.

Keyboard worked fine for 1 yr. Today my keyboard is not recognized by the iPad with current OS 16.2. The Logitech control app will open on the iPad but does not recognize my keyboard so not able to move to next screen on the app to check for firmware. I deleted and the again downloaded the Logitech control app to make sure current. The iPad has not been out of my home so no dust, dirt, etc on the contact points which grip firmly by magnets. Not getting any tech support from Logitech as I am still waiting.
