Investigation Summary

Classification: Frontend bug
Causing PR: #85229 (#85229) - Unlock landscape mode by @GCyganek (High confidence)
Related Issues: N/A

Recommendation: REVERT

PR 85229 introduced landscape mode support on iOS and Android. The regression is directly in the distance map waypoint flow, which is one of the affected files changed by this PR. The fix requires changes to the App, so reverting PR 85229 is the recommended action to unblock the deploy.

Assigned: @GCyganek (PR author), @rushatgabhane (approving reviewer), @truph01 (approving reviewer), @mjasikowski (approving reviewer)
Labels: DeployBlockerCash kept (Frontend bug). DeployBlocker is not present and should not be added.

Evidence:

• The issue body and melvin-bot comment explicitly reference PR 85229 as the linked PR.
• PR 85229 merged on 2026-04-07 and the bug is staging-only (not production), matching the merge timeline.
• The bug is in the distance map + landscape mode combination, exactly the scenario introduced by PR 85229.

Verification:

• Affected file: src/pages/iou/request/step/IOURequestStepDistanceMap.tsx
• PR 85229 modifies this exact file (confirmed via gh pr view).
• The PR restructures the layout into a flex-row split pane when isInLandscapeMode is true, placing the DraggableList for waypoints inside a constrained View with styles.flex1 and styles.pl2.
• During a long-press drag-to-reorder gesture in landscape, the dragged item is likely clipped or positioned outside the visible area due to these new container constraints.

Root Cause:
PR 85229 wraps the DraggableList (waypoints) inside a constrained View with styles.flex1 and styles.pl2 when in landscape mode. The drag-and-drop overlay for the dragged item may be clipped by this parent view boundary or rendered outside the visible viewport when landscape mode reduces available width, causing the dragged waypoint to become invisible during the reorder gesture.
