No obb found or store key to try download

So, i solved my problem. These some important things that may help someone who will have the save error:

  1. Set “Shipping mod” , full rebuild, for destribution , unclude prerequisites.
  2. After, make your keystore Signing Android Projects for Release on the Google Play Store with Unreal Engine | Unreal Engine 5.1 Documentation
    ( i tried to make key with android studio, but it did not work ).
  3. After make sure that you add expansion file ( your obb file ) in advanced mode.
  4. Dont forget to check that you install all CodeWorks that you had to.
