Can recipients submit files multiple times via the same submission link?

Yes, this is possible. Please note to set a longer expiry date for your submission link if you wish to allow your recipient to have access to your link for repeated submissions.

Can collections and submission links be deleted?

Unfortunately, this is not a feature that is available at the moment.

Why can't I upload files from my GSIB/HVB?

Highway is designed to enable file collections from citizens and not for government / healthcare / education officers to share files externally, hence uploads from certain IP address has been banned intentionally.

My agency is migrating email domains, what should I do?
