Downloaded the sims onto my new ps5 and all add on packs are missing.

Heya jenicrowth648 

First let's try the steps here to ensure all your content is fully installed to your console:

• Restore the licenses on your console 
• Go to your Game Library 
• Scroll to Your Collection
• Select The Sims 4
• Scroll down to Add-Ons and locate your DLC here
• Select the DLC in this list and select Install
• When the download finishes, let your new content install and restart The Sims
  
  

If your DLC is showing as unowned when you try this, please look over the transaction history on your PlayStation account to verify you're logging in correctly.
