 Keep the following in mind when setting up your Storage location:
 * Create a "Mihon" folder at the top-level of your storage (ex. `/Internal Storage/Mihon/`).
-* **Do not** use your device's "Documents" or "Downloads" folder as your storage location, system folders restrict & cause issues when Mihon tries to access them.

+## Storage access issues
+
+### "Invalid location" error
+This error indicates the selected storage location is invalid. Possible reasons include:
+* The app lacks Storage permission.
+* The app cannot access your Mihon storage location folder.
+
+Try these solutions:
+* **(For Android 9 and below)** In the Mihon app info or your Phone Settings, under the Permissions section, grant Mihon storage permission.
+* Grant Mihon access to your desired storage location again.
+  * Navigate to <nav to="data-and-storage">, tap on "**Storage location**", go to your "Mihon" folder and give Mihon access to that folder.
+* Create a new folder or move your existing "Mihon" outside of your device's system folders.
+  * Do not use your device's system folders (such as "**Documents**" or "**Downloads**"), they are restricted by Android and will cause issues when Mihon tries to access them.
+  * Refer to the [Storage FAQ](/docs/faq/storage) for more details.

+### Storage issues with Android 11+
+See the [Scoped Storage](/docs/faq/storage#scoped-storage) portion of the FAQ to learn how it affects **Mihon** in **Android 11+** and how to fix it.
+
+### `Cannot Access SD Card`
+* Temporarily change the Storage location from your SD card, then change it back to your original storage location and restart the app.
+* Long filepath/filenames could also trigger this issue, as Android's file manager doesn't support **>255** characters:
+  * If possible, move your "Mihon" to the top-level of your SD card or shorten your "Mihon" folder name.
+  * Remember to set the Storage location after moving or changing your "Mihon" folder.
