In IOS15, is there only one way to unmute app notifications of 1 hour/day?

Turn on a focus that allows the muted notification to show up on the Lock Screen. Then swipe left and unmute it then turn off the focus and you should be good. This is the only work around I’ve found.

Having the same issue. I accidentally muted notifications from an app from the Lock Screen. The notification thread disappeared from the Notification Center, and now I can’t unmute it. I am not getting any notifications, and it has been 3 days since I “silenced notifications for 1 day”. I have all notifications turned on for the app under the Settings, but it is doing nothing.

Yes, when the message pops up on the Lock Screen you can hold it down and it says either mute for 1 hour or 1 day and I accidentally clicked on 1day but, it won’t turn off and now I don’t get any notifications for that iMessage text chain.

I am assuming you are using the newest update (totally didn’t realize this mute thing was something until this morning when I needed it the most to ignore someone that was bugging me. So what I did is this person was on my pins of favorites in messages. I had to go to edit on the top left (once you have messages open) edit then edit pins removed said person from favorite pins. This put him back to the normal area of messages. Then I swiped left and pressed the little alarm with a line going through it. To replace him on my favorite after I unmuted him I went to back to the little yellow pin icon once you swipe left and that allows person to be added to your favorite

I presume you are referring to the Focus feature on iOS 15.

Open Control Center

Tap on Focus

Tap on Personal, Work, Sleep, or any other category that you may have set

Tap on three dots ("...")

Tap on "For 1 Hr" (If already ticked will get Unticked), You can try Tap again (Ticked), Tap again (Unticked), and so on.

Alternatively,

Tap on the category (That is enabled) to Switch off Focus.

Have the same problem, very frustrating

If they are muted you can’t see them in the notification screen. I updated to IOS 15 and accidentally turned a text chain off for one day but, is there not a way to turn it off ?
