Great question! I’ve dealt with this exact annoyance on Viber before—those sticker launch and holiday promo notifications are so intrusive when you just want to focus on actual messages. Let’s cover both the built-in hidden setting and AdAway rule methods to fix this:

Option 1: Use Viber’s Built-In Hidden Promo Notification Toggle #

This is the simplest, official solution that doesn’t require any third-party tools:

• Open Viber and tap the gear icon (Settings) in the bottom right corner.
• Select Notifications from the menu.
• Scroll down until you find the option labeled "Promotional Notifications" (or "Ad Notifications" depending on your app version).
• Toggle this switch off. This will instantly block all those sticker launch, holiday, and generic promo alerts while keeping your regular message notifications fully active.
• Pro tip: If you can’t find this option, make sure you’re running the latest version of Viber—older builds might hide this setting or use a different label.

Option 2: Block via AdAway Custom Rules #

If the built-in toggle doesn’t work for your region or Viber version, AdAway can block the underlying ad domains:

• Ensure AdAway has root access (required to modify system hosts files).
• Open AdAway and navigate to the Add Rules section.
• Paste these custom rules (these target Viber’s known promo/advertising domains):

  0.0.0.0 ads.viber.com
  0.0.0.0 promo.viber.com
  0.0.0.0 marketing.viber.com
  

• Save the rules and tap Apply to update your system hosts. Restart Viber, and those annoying promo notifications should stop appearing.
• Note: This method also reduces in-app ad loading, but won’t interfere with core messaging features or regular notifications.

Either method should solve your problem—start with the built-in toggle first since it’s the most straightforward!
