1. What is the issue? Please be detailed.
I created a form on ODK Build and downloaded it as an xml file. but it is unable to read on the browser and it is showing as bad file.
2. What steps can we take to reproduce this issue?
3. What have you tried to fix the issue?
4. Upload any forms or screenshots you can share publicly below.
Were you using the online ODK Build and did you create an account - can you log back in and re-export?
Is the file itself corrupted (what happens if you try to open it in a text editor like NotePad or TextEdit) or is the form invalid (when happens when you upload it to Central)?
We recommend you export to XLSForm as it is easier to edit and use. Read more about ODK form design at https://docs.getodk.org/form-design-intro/
