I hope this message finds you well. I wanted to inform you that we have identified an issue with the related post widget in the Gutenberg Builder not being available with the PORTO WordPress theme.
Unfortunately, the PORTO theme does not include this default-related post widget in the Gutenberg Builder. However, there are alternative options that we can explore in order to achieve similar functionality.

You can either look for a third-party plugin that provides a related post widget for the Gutenberg Builder or you can explore custom development options to add this functionality to the theme.
Please let me know which option you would prefer to proceed with, and I will be happy to provide you with further details and recommendations.
