Hi Jeff Carney / Kanin Sangcharoenvanakul,
Thank you for your feedback and the investigation.
Jeff,
Can you please confirm your broken survey created in the Survey123 website contains any special characters (e.g. > greater-than sign or < less-than sign) in any question label or choice label?
We have identified a bug in the 3.8 release with the following reproduce steps:
1. Create a new survey in the Survey123 website or open an existing survey that created in the Survey123 website.
2. In the Design tab, do any change and save the survey or directly save it without any change.
3. As long as there are any "<" or ">" characters in a question label, choice label, submit button text, the survey will be broken and you cannot open it anymore in the Survey123 website.
- In the Design tab: it keeps loading, in other tabs, you may see the error message "The survey does not exist or is not accessible."
Please let me know if this is what happened to your survey.
Thanks,
Zhifang
