YouTube Blocks Background Playback in Third-Party Browsers, Premium Feature Enforced

• YouTube has quietly blocked background playback in third-party Android browsers like Samsung Internet, Brave, Vivaldi, and Microsoft Edge.
• Previously, these browsers allowed users to play YouTube videos in the background or with the screen off, bypassing a key YouTube Premium feature.
• Testing confirms that video playback now stops shortly after the screen turns off or the user switches apps, with lock screen controls disappearing.
• The change aligns with YouTube's strategy to restrict unpaid access to Premium features, similar to crackdowns on ad-blockers and unofficial clients.
• While some inconsistencies exist, indicating a gradual rollout, the trend suggests YouTube is tightening control over background playback across platforms.

Why It Matters: YouTube is actively closing loopholes for free background playback, pushing users towards Premium subscriptions.
