For auditing and documentation purposes, it would be helpful if admins could save expired broadcast messages, including a record of when they were enabled and when they were deleted. This functionality would be useful in cases where one or more users have questions about information that was previously broadcast. For example, a broadcast may be sent out regarding planned maintenance, and if some users just click through the message, they may then have a question about whether they were notified.
Thank you for the idea. Given the low volume of support for this idea, we do not have plans to make updates in this area at this time. It is currently possible to turn off a broadcast by unchecking the Enabled option, and the broadcast will still display in the list in Settings for admin users to reference in the future. We hope that helps!
