Unable to integrate Jira


It's been a frustrating day with Smartsheet. I upgraded to a Business account, but on the Jira connector page, https://connectors.smartsheet.com/c/jira, after I sign in I get the following messages:

Unexpected error occurred. argument "content" is null

You are not licensed to use this product. Please contact Smartsheet support for more details.

The support ticket page doesn't work either, after I have filled in all the fields, the submit button does nothing.
