TL;DR - when embedding Etch e-sign links, you needed to append
&withinIframe=trueto the URL to bypass the registered user check. That parameter is no longer necessary.
Previously, each time an Etch e-sign link was opened, our system would first check if the signer email was registered to an Anvil account:
If yes, then our system would check if the user is logged in or not.
If not, then user could sign without any other prompts
Now, you no longer need to worry about this logged in/out complexity.
