YouTube videos play but only show a black screen and no sound is heard

Description of the issue: Videos on YouTube playing but show nothing.

How can this issue be reproduced? Open brave>go to “YouTube.com”>open a video>press play>video then proceeds to load (timer ticks away) but no sound is heard and the screen is dark. I am able to see channel info, comments, description, etc., but the video alone shows nothing.

Expected result: videos play as usual with picture and sound.

Brave Version( check About Brave): Version 1.79 (124)

Mobile Device details iPhone 11, IOS 18.5

Additional Information: only happened recently as of the past few hours. This morning and at lunch (8 hours ago) everything was working fine. I cleared cache and cookies, restarted my phone, opened new tabs, logged in and out of Google, and nothing has helped. Restarting my phone temporarily fixed the issue (was able to watch about 5 minutes before the video froze and would not load).

Update: after restarting my phone again (and disconnecting and reconnecting my cellular data) it seems to be fine now. Not sure if I should still leave this up since it could still be an issue?
