Hey @SHIP_DUNIYA! The React Router template from shopify app init does handle App Bridge and session tokens automatically, so your setup is likely fine. The thing with those embedded app checks is they require you to actually install the app on a development store, open it in the Shopify admin, and interact with it to generate session data. The checks then auto-run every 2 hours based on that data, so if you haven’t done that yet, that’s the first step.
If you have been using the app on a dev store and the checks are still stuck, try opening the app in a completely clean browser with no extensions. Browser extensions can interfere with the session token detection that the checks rely on. This was addressed in a similar thread where several developers resolved it by using a fresh browser profile or VM.
If it’s still not resolving after that, double-check the session token setup documentation to make sure nothing was changed from the template defaults, and you can also reach out to Partner Support via the help center chat for them to look at the checks on their end - hope this helps!
