I'm using Pro Tax OnePay (already paid and available), the eSignature request is failing when asking for T183CORP, it simply redirects to the Pricing page. Any idea?

Hi jessicaylz-gmail,

Thanks for reaching out to us here.  Welcome!  Receiving an error when using the esignature feature, is concerning.  I encourage you to contact our ProTax Customer Care team outside of this forum.  They'll be able to look into this in more depth from their end, and escalate if for further investigation as they see necessary.

Please reach out again, if you have any other questions.  We would be glad to help!
