General Feedback on 6.2.3/6.2.4

I've had two clients update their own ReadyNAS devices to 6.2.4 on their own and lose their Egnyte storage sync share access after the update -- other shares on the device will mount, but the Egnyte share is not available or not found, though it does appear in the list of shares on the device.

The first occurrence was last week; I ended up progressively downgrading to 6.2.3 and then back to 6.2.2, at which point users could again mount the Egnyte share.

Today another client had the exact same issue, I skipped down to 6.2.2 and again that was the solution -- exactly the same behavior.

BTW: is there a way to disable the nag screen for updating the firmware? Or like set it to check every x months? Sometimes users need to log in to do basic admin tasks like add or remove new Egnyte users, and the update nag is apparently just super tempting. :) Alternate solution would be a non-admin interface for users to do this, or a sub-admin management role, I suppose. The user story here is, I would like to be able to switch from automatically to manually checking for updates. (Found some info about such a feature for v4 but not yet for v6.)
