# FAQs and Troubleshooting

***

<details>

<summary><strong>Why doesn’t Deep Linking work in Previewer?</strong></summary>

Preview URLs don’t support Deep Linking—always test on your Published App.

</details>

<details>

<summary><strong>Why doesn't Deep Linking open my installed PWA?</strong></summary>

Installed PWA's are a website that's been downloaded and saved to your device, providing an app-like experience. Think of them like a bookmark of a Website.&#x20;

Since these are just a reflection of the browser and not actually an App, they will not open with a Deep Link. Instead, a new browser instance will open in the default browser.&#x20;

</details>

<details>

<summary><strong>Can I use Deep Linking in Legacy Apps?</strong></summary>

No. Legacy built Adalo Apps will not support the new Adalo Deep Linking Feature. You must update your app to Responsive to implement it.&#x20;

</details>

<details>

<summary>Is Deep Linking an action?</summary>

Deep linking is not an action. Deep linking is a standalone Adalo feature, and is managed separately by the Adalo infrastructure and team.&#x20;
