Hi there! I see you're experiencing a purple blank screen when trying to use the Tubi app on your device running Linux with a WebKit browser. Let's work through this together so you can get back to streaming.

To start, could you tell me if the purple screen appears right after launching the app, or does it happen during playback? Also, have you already tried refreshing or restarting the app or the device?

Meanwhile, here’s a step-by-step guide tailored for your setup:

1. Refresh the Browser & Clear Cache:
Since you are on a WebKit-based browser on Linux, start by refreshing the page using Ctrl+R or the browser’s refresh button. Then clear the browser’s cache and cookies for Tubi to remove any corrupted temporary data that may cause this issue.

2. Close and Reopen the Browser:
Completely close your browser, ensuring no Tubi-related tabs remain open, then reopen it and navigate back to Tubi’s website.

3. Check Internet Connection:
Make sure your internet is stable. You can run a quick speed test or browse other streaming sites to verify connectivity.

4. Update Your Browser:
An outdated browser can cause display problems. Check if your WebKit browser has updates available, and install those.

5. Disable Browser Extensions:
Sometimes, ad blockers or privacy extensions can interfere with video playback. Try disabling these extensions temporarily to see if the purple screen resolves.

6. Try a Different Browser:
If the issue persists, test Tubi on another browser available on your Linux system (like Firefox or Chrome based browsers) to see if the problem is specific to WebKit.

If these steps don’t fix the purple screen, you might consider fully uninstalling and then reinstalling the Tubi app if you are using a desktop app version. Also, restarting your entire Linux device helps reset any stuck processes.

If you’ve tried all this and still face the purple screen, let me know. We can look into more advanced troubleshooting next, like checking for DRM or video driver issues, or verifying if there’s an ongoing service status problem on Tubi’s side.

Are you able to try these steps? Let me know how it goes!
