Hi there! I see you're having trouble with the Tubi filter on the JustWatch app—it’s showing movies, but Tubi isn’t listed as an option when you select those titles. That sounds a bit odd.

To help you best, could you please tell me:
- Are you using the JustWatch app on your Linux device through a browser, or is this through some app wrapper on Linux?
- Have you noticed if this issue started recently or has it been ongoing for a while?
- Have you tried filtering by other providers, and do their filters work correctly?

While you check that, I want to share what I found about this issue: It appears there has been a known problem with Tubi not fully showing up in filter options on JustWatch after some updates in 2023 and even continuing intermittently through 2024 and 2025. Users reported Tubi does not list as a provider filter properly, though its content may still appear under broad searches. JustWatch has acknowledged this and promised fixes in the past, but it seems some glitches remain1.

Here’s a step-by-step approach to try:

1. Clear Browser Cache and Cookies (if you're using a browser on Linux): Sometimes stale data can cause filters to misbehave. Close the browser, clear cache and cookies, and then reopen JustWatch and test the filter again.

2. Check for App Updates: If you are using an app on Linux (e.g., via snap or a package), ensure it's updated to the latest version, as some fixes might have been pushed.

3. Try a Different Browser or Incognito Mode: This isolates if browser extensions or settings might interfere.

4. Check Regional Settings on JustWatch: Sometimes content availability and filters differ by country. Ensure your region is set correctly.

5. Use the General Search Feature: If Tubi filter is broken, try searching for a movie and see if Tubi is listed in the available providers on the movie's page.

If after trying those steps Tubi still doesn’t show properly in filters, the issue may be on JustWatch’s side, needing a fix in their system. You can report this directly via [email protected], referencing that the Tubi filter isn’t showing up on Linux and browsers, so they can prioritize the fix.

Let me know how it goes after these steps, and if you'd like I can guide you through any of them in more detail! Are you satisfied with this approach so far?
