*THIS ISSUE HAS BEEN RESOLVED*
We have been alerted to a sensitive issue regarding accepting proposals and signing them through the iPhone app. We released an update to our contracts (http://help.shootq.com/entries/36490474-New-Features-May-7-2014-) which broke how the iPhone app stores and displays the studios signature within shootq.com. When the contract is accepted from the iPhone app, it does book the shoot, but the signature is not stored in shootq.com.
We are aware of this issue and are currently investigating it and working to fix it. We will post updates here as we have them. In the meantime, we strongly suggest that you do not accept and sign proposals from the iPhone app. You can log into www.shootq.com from your computer to accept and sign the proposal without any issues.
Thank you for your patience while we work to troubleshoot and correct this issue as soon as possible.
