We are aware of the problems preventing Mvelopes members from launching the application. As soon as we have an update, we will post it here
UPDATE: Mvelopes is now up and running for all members. Following yesterday’s announcement of a free version of Mvelopes, we have been experiencing extremely high demand. This afternoon, our team responded to an incident affecting member’s ability to launch the application. We have taken steps to resolve this issue and are working to prevent this from happening in the future. We expect the demand for Mvelopes to remain high and are committed to ensuring a great customer experience for our current and new members. Thank you for your patience.
