| Criteria | +Conformance Level | +Remarks and Explanations | +
|---|---|---|
| 1.1.1 Non-text Content (Level A) | +Partially Supports | +Android: Most icons, buttons, and other elements announce meaningful information in the flows tested. The Instagram hashtag count control does not announce meaningful text. iOS: Not evaluated. | +
| 1.2.1 Audio-only and Video-only (Prerecorded) (Level A) | +Not Applicable | +Both platforms: The mobile apps do not present prerecorded audio-only or video-only content. | +
| 1.2.2 Captions (Prerecorded) (Level A) | +Not Applicable | +Both platforms: The mobile apps do not include in-app video content. | +
| 1.2.3 Audio Description or Media Alternative (Prerecorded) (Level A) | +Not Evaluated | +Not yet formally evaluated. The mobile apps are not understood to include prerecorded media content (see 1.2.1 and 1.2.2); this will be confirmed in a future review. | +

| 2.1.1 Keyboard (Level A) | +Not Evaluated | +For native apps this criterion covers external keyboard input and platform switch control (Switch Control on iOS, Switch Access on Android). Not yet formally evaluated on either platform. | +
| 2.1.2 No Keyboard Trap (Level A) | +Partially Supports | +Android: Focus could be moved away from all components in the flows tested, except when exiting the composer, where focus could not be moved away. iOS: Not evaluated. | +
| 2.1.4 Character Key Shortcuts (Level A — WCAG 2.1) | +Not Evaluated | +Not yet formally evaluated on either platform. | +
| 2.2.1 Timing Adjustable (Level A) | +Not Evaluated | +Not yet formally evaluated on either platform. | +
