Summary:

1. Some users are intermittently experiencing loading screen issues when trying to send correspondences, such as rejecting a candidate. When they experience this loading screen, the message doesn't get sent to the recipient (but rejects the candidate) and the loading circle doesn't resolve, so they have to close the browser down.
