weird. I just tried and DO get ringtones … I normally keep it toggled “off” because I don’t really want them to the aids, but they do go to aids if I turn them on… as I said before, one of th ios13 iterations turned the text notifications OFF - not sure what Apple plans to do - would be nice if they gave folks the option (like the “play ringtones” ) …
Can I assume you tried all the usual , reboot the phone, repair the hearing aids, check to make sure the “silent” switch on side of iphone isn’t turned on…
