When I go to the three dots menu in our ongoing conversation and I select notifications it tells me to change the notification sounds " first turn on notifications for this conversation". Clearly I turned them off unintentionally does anyone know where this function is..???? It is my mom, and she likes quick responses and most of the time I haven't a clue that she messaged me. Thank you!
Go into the first screen of the messages, where you see all the messages from everyone, press and hold the one with your mom, on the bottom left you might see that you muted the notifications for that one conversation.
