Number keypad after initial call (for passcodes, menu selection, etc.) DOES NOT WORK.
I have an iPhone 11 and after I call into work telecons, zoom meetings, or access other numbers, all of which are preliminarily successful, I'm asked to enter further keypad numbers such as passcodes, menu entries, etc to gain entry into the telecons, meetings or other department. For some reason, my screen keypad no longer recognizes me touching the screen, and I get a "call failed" screen because none of the information I press in is received by the other end. What is wrong? Do I need to reset something?
