Unable to share files with collaborators from zoho docs. When I use the share with "collaborators only" by adding their email address and then pressing share nothing happens. An email is not received and they are not added to a collaborators list. The same issue exists when using the share using a password. However, after adding their email address and clicking send an "mail sent successfully" notification appears but an email is never received by the recipient. When using zoho mail to send an email to this recipient the transaction is almost instantaneous. There is some issue with zoho docs.
