Hello Daniel, thank you for getting in touch and for your support!
You cannot plug a Texture Sample node directly into the Texture input of the Parallax Occlusion Mapping node, you specifically need to use the Texture Object node.
You can find more information on the
POM node in our wiki page, and I also recommend that you check out our working sample using this technique in the following folder: AmplifyShaderEditor/Examples/Official/ParallaxOcclusionMappingPOM.
Regarding Texture Arrays, the POM node supports the use of 2D texture arrays after enabling its "Use Texture Array" Parameter, through a
Texture Object node with its Auto-Cast Mode set to "Locked to Texture 2D Array", please refer to the screenshot below.

You can find some additional information on texture arrays in the
Unity Manual.
Please let me know if this information helps, don't hesitate to get in touch if you have any follow-up questions, thanks!
