YouTube Thumbnails not Loading

[Hxnd]

Description of the issue:

YouTube thumbnails are not loading on Brave Mobile (specifically m.youtube.com), they are just grey boxes.

How can this issue be reproduced?

1. Navigate to youtube.com
2. Wait to be redirected to m.youtube.com
3. Sign into your YouTube Account
4. Scroll the site and notice none of the thumbnails load

Expected result:

The expected result is to have all the thumbnails load normally while browsing YouTube while signed in.

Brave Version( check About Brave):

Brave 1.65.126, Chromium 124.0.6367.118

Mobile Device details

Google Pixel 7 Pro
Android 14; Build/API A.240405.002

Additional Information:

I have tried with Brave Shield down, a private tab, clearing all cache & cookies inside Brave, clearing cache via android app settings, disabling all content filters, and reinstalling the app but the issue persists. When using the desktop version of the site in Brave Mobile the thumbnails load normally. When I make searches while signed out of YouTube the thumbnails load normally. Not sure if it has something to do with the m.youtube.com domain & my account interaction or something else entirely.

Any help would be appreciated.

Thanks!

@Hxnd,
Thank you for the detailed report.
Just to make sure I understand the exact behavior, this issue only occurs when you’re actually logged into your Youtube account? If you login to YT in another browser and go to m.youtube.com does it display correctly there?

[Hxnd]

Correct. Only when logged into my YouTube account. Regretfully, I forgot to test other browsers. Trying with Chrome now and the issue seems to exist there too. I can make another YouTube account and see if a new one suffers the same issue. Thanks.

[Hxnd]

New account doesn’t have any issues on either browser.

Well that’s admittedly very strange. Maybe its a Youtube specific issue? I will ask a couple team members and see if they know anything about this.

[Hxnd]

Thanks. It could certainly be a YouTube specific issue. I made a forum post on YouTube Community but I’m not hopeful.

This issue has self resolved. Thanks, Mr. Mattches.
