@la-sanchez, thank you for opening this issue, but this is a known issue and noted in issue #11231. I have already looked into this and didn't find a workaround outside of adding the subscription level feature flag, however I will look at @favoretti PR closer later today. 🚀

@WodansSon Ok thank you very much, feel free to close it then if needed.
