Hi @base007,
Yes, the featured image is not available in Radiate Free Version but we have offered an option via Radiate Pro to enable the featured image in a single post as well as pages.
We always try our best to help our users regarding their issues. While checking, I do not find any support query related to this in the Radiate support forum. If you have submitted your query in the support thread then we could have helped you.
If you still would like to add a featured image in a single post then you can contact us via https://themegrill.com/contact/ Chat Support so that you can help you with the featured image.
Best Regards,
Premi J.
ThemeGrill Support Team.
