Mp3 not playing

Hello. I downloaded some shared decks online and there are .mp3 files. I use both my computer and my phone for the desktop version and they both do not play the .mp3. When I go to the sample page for the shared deck online, both my computer and mobile devise is able to play the audio. It’s only when I go to my profiled deck that it does not play. I use safari on my mobile and chrome on the computer. Why is it not working once it is downloaded?

After importing a shared deck, and confirming the sound files play inside Anki, you need to sync and wait for media to finish syncing: Media files may take time to sync - Frequently Asked Questions
