When marking and closing an issue as a duplicate the issue that’s kept open shows incorrect dialog that it’s a duplicate itself

On web, it dialogs fine that the other issue is a duplicate of it. But in the app it shows as a duplicate of itself. Notice the different issue numbers in the 2 screenshots.

I also had trouble itself actually closing the duplicate in the app and had to use web to do so.

On the web, the duplicate relationship is handled correctly and links to the original issue, but in the app it appears to incorrectly reference itself as the duplicate. That inconsistency definitely shouldn’t happen. The fact that you also couldn’t close the duplicate from the app and had to switch to the web UI is especially helpful context.

This seems like an app-specific state or sync issue when resolving or displaying duplicate links. We’ll take a closer look at how the app determines and updates duplicate issue references to make sure it mirrors the web behavior correctly.

Note that this is still present and also affects Android.
