Common Issues

• Validate signature freshness and role.
• Confirm meeting identifier and passcode mapping.
• Validate host token (ZAK) for start path.

2. Delegate callback gaps

• Ensure delegate/controller registration happens before feature usage.
• Keep coordinator/service objects strongly referenced through session lifecycle.

3. Custom UI regressions

• Verify default UI still works to isolate custom layer issues.
• Re-check rendering and feature-controller dependencies after SDK upgrades.

4. Version drift

• Re-run feature-level tests on breakout, share, annotation, and AI companion modules.
• Compare API reference map for renamed or newly required interfaces.
