I use LTI links in my LMS. Some students report an 'Invalid State' error message. What could case this error?

This error message has been reported to SoftChalk Support. In troubleshooting the Invalid State error message, we’ve found there could be a few causes for the error:

iPad and iPhone running older iOS.
We would recommend updating the iOS to the most current version.
There may be an issue with content entered into the ‘state’ field within the LMS profile.
We suggest that you clear or correct the ‘state’ field in your LMS profile to see if that resolves the issue
