the console.serverless-stack.com endpoint when starting a serverless-stack keeps stuck on "syncing metadata"

hmm.. did this start happening after adding/removing a stack?

Not sure if relavent to you, but I had the same issue and it ended up being because I was using the brave browser and it was blocking certain scripts.. I had to turn off shields up for that site

Also happened to me when I had a legacy stack deployed which didn't match my current infra definition. I believe the issue was patched though, so ensure you are on latest version of SST to discount that.

@Michael Wolfenden that was it, i was using brave.
