Invalid appid when accessing the API

I’ve created a couple different applications with separate appid’s and I get the same error anytime I access the API - “invalid appid” - this happens no matter how I try to access the api, including via a url in the browser. Is anyone else experiencing this?

I have also been receiving that same error. I cannot seem to get it to work. I just created the app today, so I’m wondering if it takes some time to propagate to all servers.

Yes, it seems this can be caused by a propagation delay. I created an App ID and got this error for the first few minutes; then it started working.
