IOS – sms/imessage’s allert don’t work for one contact

alertiosmessages

I have an iPhone 11 on 13.5.1 iOs. Suddenly, the alerts of imessage don't work, for one only person. There is no budge for new message in the chat (on the main app, where all the chats are).
This specific contact is not on the "Do not disturb" and the alerts are on, but my iPhone neither rings nor has a banner for the new message. I've already tried to delete the chat, delete the contact, restore the settings but nothing of these worked. What can i do?
Thanks in advance.

Edit: when I open the message from this contact, he cannot see if I read the message or not. The status of the message is “delivered”.

Best Answer

is it possible that you have muted or limited the alert on this contact?

Hide Alerts on ios contacts via imessage

Or, if you have added them to the Spam or Block, then alerts would be suppressed.
