Report a problem from inside the app
If a support build shows the Diagnostics card, open Resources, expand Settings, tap Copy Diagnostics, and paste that copied text into your email. The diagnostics payload helps identify the build, device, language, startup phase, current tab, and recent launch events. It does not include journal body text.
In the normal App Store build, Diagnostics may be hidden. If you do not see it, just include your device model, iOS version, affected screen, and the shortest steps that reproduce the issue.
