Sure, I can help you with that. YouTube playlist visibility issues can be due to several reasons. Here are some steps you can follow to address this:

1. **Check Playlist Settings**: Make sure your playlist is set to Public if you want everyone to see it. If it's set to Unlisted, only people with the link can view it. If it's set to Private, only you can view it. You can change these settings by going to your playlist, clicking on 'Playlist Settings', then 'Privacy'.

2. **Check Video Settings**: If your playlist is public, but some videos in it are set to Private or Unlisted, those videos will not be visible to others. You'll need to change the video settings individually.

3. **Check Copyright Issues**: If a video in your playlist has been removed due to copyright issues, it could affect the visibility of your playlist. Make sure all your videos comply with YouTube's copyright policies.

4. **Check Community Guidelines**: If your playlist or any videos in it violate YouTube's community guidelines, it could be hidden or removed. Make sure your content is in line with these guidelines.

5. **Check for Glitches**: Sometimes, a simple glitch could cause visibility issues. Try logging out and logging back into your account, or try viewing the playlist from a different device to see if the problem persists.

6. **Contact YouTube Support**: If you've tried everything and your playlist is still not visible, it might be a good idea to reach out to YouTube Support for help. They can help identify and resolve any potential issues with your account.

Remember, changes you make may take some time to reflect. So, give it some time before checking if the changes have been effective.
