Keypad not working during call iphone11

Having the same issue this morning - automated answering systems at Walmart/CVS/Walgreens not recognizing my keypad tones... Press 1 for pharmacy - Me 11111111111 😡 Even voice option not working?! I then hang up and call my daughter - no issues!

What happens when you try?

Did you already try a "forced" restart of your iPhone?:-> Force restart iPhone – Apple Support
