Hi Howard,


Do you know when this will be pushed out to the clients through the auto update?  Or is this a manual install update?

Is this version the current version that is available for download? If not can you post a download link for this version of Box Sync?

When I make the TLS-check this shows up (see screenshot). Does this mean that the new TLS1.1 won't work from 25th of June or is everything ok?And if not, what shourd I do?
