Why am I seeing an "Invalid SSO Response" error? V6

If you encounter an Invalid Single Sign On (SSO) Response error when trying to sign in to InVision V6, Studio, Craft, or DSM, there is most likely inaccurate data in the SSO settings for InVision. To solve the issue, the owner or an authorized admin on your Enterprise team will need to work with your internal IT team to gather the necessary metadata that InVision Support must have to update the SSO settings.
