User reviews

This tool is incredibly handy, but recently it's been unable to connect to the SDK for a few weeks now. The error message consistently reads 'Trying to connect to page's GrowthBook SDK', yet it never successfully connects, rendering the tool useless. Please address this issue promptly!

Seems like it could be useful. Icon is greyed out / not accessible. Also shows an error in the console.
