After a recent update - my iframe code doesn’t work.
We recently updated TheBrain Web Client which may cause an issue for existing embedded Brains. You may be seeing a blank screen or an error that says Sorry, there’s nothing at this address.

To fix this issue, edit the iFrame code used to embed your Brain:
Old Format:
<iframe width="800" height="600" src="https://app.thebrain.com/embed/1c9d0bdb-8e55-43b2-ac53-959e4c2c8864" frameborder="0"></iframe>
New Format:
<iframe width="800" height="600" src="https://app.thebrain.com/brain/1c9d0bdb-8e55-43b2-ac53-959e4c2c8864" frameborder="0"></iframe>
