 • Head to your device settings
+
 • Open up "Apps & notifications" (This name depends from ROM to ROM)
+
 • Find 'Media storage' app and clear storage (both data and cache) of it.
+
 • Then open Retro Music app and manually scan your music from your storage. 
+
 • Reboot the device to refresh media store (Not sure if this is necessary)
 
 NOTE: Don't panic when you will open Retro Music and see "Zero" songs there in the library. It's because you cleared Media Store which is responsible for recognising files on your device.
+
+
+#### Q: I can't find folder menu anymore after latest update?
+Head to settings -> personalise. And select folders from "library categories". If there is option of folders, tap on reset and select folders.
+
+
+#### Q: After updating the app to latest version, font got removed. Why?
+Retro Music's font have now been replaced with system font now, which means the default font your system uses will be used by Retro too. It fixes all font related issues you used to face/are facing in the app. 
+
+If you think the font looks ugly, then you just need to change the default font from your Android settings (or use any Magisk module). If you can't, there's nothing we can do about it.
+
+
+#### Q: How to export playlist:
+In your built-in music player, there should be an option to save those playlist as file. Save them and import from file manager by opening it into retro music.
+
+Note that those playlist must be of your offline music only since retro music is offline music player not an online music player. So if your playlist are of online music, it can't be opened on other offline players nor can be exported
+
+
+#### Q: How to restore/import playlist:
+Retro Music will automatically detect any playlist file when that playlist file is stored in InternalStorage/Playlist. However, if it doesn't, just open "file manager" and open that playlist file with Retro Music.
+
+For restoring playlists, the location of songs must be same in both Playlist file and in your storage. For example, your music is in "Internalstorage/Music" and playlist file has songs location "Internalstorage/Songs". Then it will not going to work since both these location are different.
+
+
+#### Q: Adding songs to playlist or marking them as favourite are making app crash. Why?
+It's a known issue with only android 10 with its media store API when songs are in SD card due to introduction of Scoped Storage by Google. The issue have been created on Google Issue Tracker by many users. Many other players which doesn't have this issue are using a custom database for storing playlist. We will soon be implementing a custom database for playlist to fix this issue!
+
+Workaround: You can move all songs to internal storage to fix the issue.
