# Samsung TizenOS. Troubleshooting

#### The Buzzblender app doesn't appear in Samsung Store

If you search for Buzzblender but can't find it, check these common causes:

<details>

<summary>Your TV may not support Tizen OS</summary>

Not all Samsung TVs run Tizen OS. Very old Samsung smart TVs (before 2015) and some budget models may use a different operating system. Check your TV model specifications on Samsung's website to confirm it runs Tizen OS. Buzzblender requires Tizen OS to work.

</details>

<details>

<summary>Regional availability</summary>

The Buzzblender app may not be available in all regions. If the app doesn't appear in your Samsung Store, your region might not support it yet. [Contact Buzzblender support](https://buzzblender.com/contact-us/) to check availability for your location and get assistance.

</details>

<details>

<summary>Samsung Store needs an update</summary>

An outdated Samsung Store app can cause search issues. Press the **Home** button, navigate to **Apps**, then press and hold the **Select** button on the Samsung Store app to open the options menu. Choose **Update** if available, then try searching again.

</details>

<details>

<summary>Your TV firmware is outdated</summary>

Old TV firmware can prevent new apps from appearing. Go to **Settings → Support → Software Update** on your Samsung TV and install any available updates. After the update completes, restart your TV and search for Buzzblender again.

</details>

#### The activation code doesn't work

<details>

<summary>Code already used or expired</summary>

Activation codes are single-use and expire after a short time. If the code doesn't work, close and reopen the Buzzblender app on your TV to generate a new code, then enter the new code in your dashboard immediately.

</details>

<details>

<summary>Typos or spacing errors</summary>

Activation codes are case-sensitive and must be entered exactly as displayed. Double-check each character, and make sure you're not accidentally adding spaces before or after the code.

</details>

#### The app won't connect to my account

<details>

<summary>Check your internet connection</summary>

Your TV needs an active internet connection to communicate with Buzzblender's servers. Test your connection by opening another streaming app (like YouTube or Netflix) on your Samsung TV. If those don't work either, troubleshoot your TV's network settings in **Settings → Network**.

</details>

<details>

<summary>Firewall or network restrictions</summary>

If your business network has strict firewall rules, they may block the Buzzblender app from connecting. Try connecting your TV to a mobile hotspot temporarily to test if the issue is network-related. If the app works on a different network, ask your IT team to whitelist Buzzblender's domains.

</details>

#### Content not appearing on my TV after setup

<details>

<summary>Playlist not assigned to your screen</summary>

After creating a playlist, you must assign it to your screen. In the Buzzblender dashboard, go to your playlist settings and ensure it's assigned to the correct device. Without assignment, the TV won't receive the content.

</details>

<details>

<summary>Schedule not active yet</summary>

If you scheduled content to play at specific times, check that the current time set on TV falls within your scheduled hours. Content only appears during its scheduled time slots.

</details>
