What are the limitations of using Zoho Sign for digital signatures?

The following limitations apply when you use Zoho Sign for digital signatures: 

• You can add a maximum of 3 signees by clicking +Add Signee.
• When you have multiple signees, only after the first signee signs, the second and third signee will be able to sign.
• When you have multiple signees, if the first signee discards the document then the second and third signee will not be able to sign.

You can use the Delete icon you can delete the signees added, prior to sending the documents for signature and not once sent.
