Hello. I have tried every steps that are recommended regard of an app that is not responding. But it is not fixed, how can I solve this problem?

Hi hanbi129,

Thanks for posting in Apple Support Communities! If you've tried all the steps in the linked article (If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open) and the issue continues, we suggest reporting the behavior you're experiencing. For third party apps downloaded from the Mac App Store, follow these steps to contact the developer:

1. "Open the App Store on your Mac.
2. Click the sign-in button  or your photo. 
3. A list of apps appear. Click the app that you want. If you can't find the app, use the search bar.
4. The app's product page appears. Scroll to the Ratings & Reviews section, then click App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID.

"

These steps can be found in the article How to contact an app developer and will help you get your issue reported. If you didn't get the app from the App Store, follow this guidance instead: Contact a third-party vendor.

For issues with Apple apps, tell us more about what's happening with the app when you try to use it, and which app is affected so we can assist.

Cheers!
