Screenshots that show a more polished UI than the shipping build, marketing renders dressed up as device captures, or features absent from the codebase trigger App Store rejections under Guideline 2.3.3 (Accurate Metadata). Users who install based on inaccurate screenshots leave 1-star reviews within the first session, tanking conversion and store ranking. Missing required device sizes (6.5 inch iPhone, 12.9 inch iPad) block submission outright before review even begins.
High because inaccurate or missing screenshots are a top-five App Store rejection cause and a documented 2.3.3 violation.
Capture screenshots directly from a device or simulator for every required size, then commit them to fastlane/screenshots/<locale>/ so review state is reproducible. Automate capture with fastlane snapshot for iOS and fastlane screengrab for Android so screenshots regenerate from the current build on every submission rather than drifting out of sync.

Check for: (a) screenshots that appear to be from a different, more polished version than the current codebase (e.g., screenshots show a feature not present in any source file), (b) screenshots with placeholder content (lorem ipsum visible in the screenshot filename metadata or alt text), (c) no screenshots at all in any standard location, (d) screenshots that appear to be renders or mockups rather than actual device captures (filename patterns like mockup_, render_, marketing_ suggest marketing assets rather than device screenshots), (e) for Expo, check app.json or eas.json for any screenshots configuration. Also verify screenshot filenames include device type indicators — reviewers need screenshots for specific required device sizes. For iOS: at minimum 6.5" iPhone (1284×2778 or 1242×2688) and 12.9" iPad if the app supports iPad. For Android: phone screenshots are required; tablet screenshots recommended. Count every screenshot in the metadata directory and enumerate each. For each screenshot, classify as matching current UI or outdated/misleading.preview-video check in Review & Submission verifies any video assets match the current UI alongside the screenshots validated here."No screenshot files found in any standard location — screenshots must be present in App Store Connect before submission" or "Screenshots appear to be marketing mockups (filenames: 'marketing-render-01.png') rather than actual device captures".fastlane snapshot (iOS) or fastlane screengrab (Android) to automate screenshot capture
Store screenshots in fastlane/screenshots/ or src/store-metadata/screenshots/. Regenerate from current builds using fastlane snapshot or manual capture.
