This one is turning into a head scratcher (yes, have googled). I just noticed that if I make a call requiring me to navigate a menu (press 1 for sales, 2 for service etc) I push the number on the phone but the press is not being recognised at the other end. The tone does sound quiet to me when I press the appropriate button but I can't for the life me find out where to adjust the DTMF dialling volume.
Can anyone help?
Thanks
I had exactly the same issue with V30+. Seemingly, turning WiFi calling off helped, give it a try.
