There are a few reasons why your PlayStation 4 may not be taking discs. One reason is that the PlayStation 4 has a built-in DVD player. If you have an optical drive, it may be able to read discs, but if you don’t, your PlayStation 4 may not be able to play them. Another reason is that the PlayStation 4’s firmware might be outdated. If it is, then the disc drive might not work properly and won’t allow you to play discs. Finally, there could be some other issue with your PlayStation 4 that we can’t identify yet. If you have any questions or concerns about this issue, please let us know and we’ll do our best to help you out!
