SIgn in with Blockstack not working

After much frustration and time I have finally installed the blockstack browser and have it running. But now, when trying to log in to various blockstack apps via blockstack. I am redirected to a page that says this ‘You’re here because you clicked “Sign in with Blockstack” and you don’t have the Blockstack app installed.’

i have the same problem. i got the blockstack demo app working but it dont work if i use it in an iframe from different port. i guess the security is too tight, it would be easier to just inject js to the browser app, but that would bypass the cros api
