Hi @KetpuntoG, this is a known issue with the build pipeline. Could you confirm whether or not these notebooks look similar to what you are seeing here?

[KetpuntoG]

No @co9olguy , the problem looks different. In the link you passed me it seems that it doesn't understand the cells as python but they appear. When downloading the notebooks from pennylane, the code cells disappear.

Here is a comparison of what the web shows and what the download shows:

This is very strange 🤔 I wonder if the affected demos share anything in common that causes this (the python cells to be ignored).
