[iOS] Asset bundles loads with no textures

Hi,
every asset bundle I generate and load form OSX / iOS devices comes without the textures attached to the materials, while on Windows Unity editor and Android devices they works correctly.
The asset bundles are generated platform specific.

I found this question has been asked in the past and there is even a closed ticked https://issuetracker.unity3d.com/is...ence-to-textures-if-loaded-from-asset-bundles but the issue is still present.

Is this a known issue? Is there a fix for this?

Thanks everyone in advance and have a nice day!
