Hi Abigail Stephens. Yes. This has been resolved:
It is not currently possible to limit/allow a second survey being sent via web app within the settings of Survey123 Connect.
Having said that, we do have an existing enhancement in our internal repo, which I will add your comments to.
No, you can open a survey made in Survey123 Connect in the web app; there's a link provided when you sign in to the Survey123 website, that you can then distribute to whoever needs to fill it out.
Be aware that your survey won't look exactly the same, however, and depending on your survey not everything you need may be supported.
It's not yet possible in Connect, but we hope to make it possible. Until then, the ability to prompt the user to send another response is only available in the web app.
