Focus ios 15 silence messages keep ring tones
I'd like to be able to receive calls from certain people when I sleep (family, in the event of emergency) but not receive text tones from, say, the elderly sister who messages from Florida without considering it's three hours earlier here (and never will). Is there a way to have a focus that maintains ringtones but silences text tones. Thanks for any suggestions.
This is just for my phone as everything else is not in the bedroom.
