Pull request overview
This PR aims to reduce flakiness in Detox E2E tests by centralizing timing budgets, adding a “reload RN with sync disabled” recovery helper, and using those utilities in AppleApp E2E flows to avoid hangs when RN debug surfaces keep the app non-idle.
Changes:
- Added shared Detox timing constants (
DETOX_TIMING) and reused them for polling/timeout budgets. - Introduced
reloadReactNativeIgnoringSync()to reload RN without waiting for app idleness. - Refactored AppleApp Detox helpers to scroll embedded RN into view and use the new reload + timing utilities.

Summary
This PR stabilizes flaky E2E tests by scrolling the embedded RN surface into view and reloading with Detox sync disabled, so recovery doesn’t hang until the Jest timeout while waiting for an idle app that never settles due to RN debug animations.
Test plan
CI green (few consecutive re-runs of E2E succeed).
