Hi @Masoud21,
I'm sorry to hear you're having some issues updating the Airbnb app on your device! I found this help center article 👈 that explains how to update it, and it mentions that you need to make sure your device is up to date with the latest version of iOS or Android.
At the moment, the app requires iOS 16.0 or later in order to run -the latest requirements can be found on 👉 this page. Are you able to update your device to that version?
I hope this helps. 🙂
