Unpin a DELETED message?

Hi FuzzFactory,

Thanks for posting your issue in the Apple Support Communities! We'd be glad to see how we can help you with this. First, we'd like to ask you a few questions to get a better understanding of what's going on. Do you mean that you had deleted a conversation that was pinned in your Message app, but it's still appearing as a Pin? If this is true, are you able to edit your Pins by using the steps in Use Messages on your iPhone, iPad, or iPod touch?

Once a conversation has been deleted, it should automatically be unpinned. However, if your Message app still isn't behaving correctly, we'd recommend following the troubleshooting steps outlined in If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open.

Let us know how this works out for you. Cheers!
