0 of 4 completedCapture the exact failure state
ReversibleNote the exact update version, accessory or backup date, and confirm the feature worked immediately before it. Expected behavior: arrange supported app windows on the current iPad and display configuration.
Isolate the component boundary
ReversibleConfirm the model and software support Stage Manager and test two Apple apps. Test with the new accessory removed, or check the update's known-issues note for the exact symptom. Boundary to separate: model/iPadOS eligibility versus app support, display and multitasking setting.
Correct only the proven cause
ReversibleEnable multitasking controls, update the unsupported app or remove the external-display boundary. Reset the one setting the update changed, or replace the incompatible accessory.
Verify and stop safely
ReversibleConfirm normal operation with the change present for one full day of typical use. Do not reset the iPad for a feature the model does not support.
