Bad content update and DNS app-id woes

Hey all, my org was affected by this so figured i would share:

Seems like there was an Apps and Threats update that affected DNS application behavior causing all dns-base traffic to longer filter on parent DNS app - 8585-7440 on 2022/06/22

This seems to have been correct in 8586-7445 on 2022/06/24

However i have observed an issue on multiple firewalls where 8586-7445 download integrity was questionable, and the corrupted content update failed to install. I needed to delete, re-download, and manually install on affected firewalls.

Hope this helps.
