Browser extensions or add-ons such as AdBlock can sometimes interfere with Philo Edu. Successfully viewing Philo Edu in a private or incognito browser window is indicative of this issue.
To test, repeat these steps for every extension or add-on:
- Disable the extension or add-on.
- Restart your browser.
- Open Philo Edu.
Once you've found the culprit, consider changing its settings so it is disabled when watching Philo Edu, or remove it entirely.
