07/15/2025, 3:50 PMI've implemented the Javascript SDK in my NextJS application. I have features rendering during SSR which is my desired use for them, but now I want to debug on the client and swap out variants using the Chrome Extension. Is it possible to override the flags during SSR? It seems like I should be able to see the variant override when I reload the page since my uuid is static, which I have confirmed. However I never see the variant load in unless I'm on localhost.

07/15/2025, 3:51 PMDo I need a connection to back end SDK for that to work? I would think it would sync my override to the cloud instance and serve the user with this uuid the correct variant. Is that not how it works?
