We’re temporarily postponing updates to version 20.5
Microsoft today sent out this announcement regarding updates of Microsoft Dynamics 365 Business Central for SaaS customers:
We’re temporarily postponing updates to version 20.5, and your tenant has one or more environments currently scheduled to receive this update.
If you have an environment scheduled to receive an update while updates are postponed, your environment will not be updated automatically, but will be rescheduled to seven days after the originally scheduled date. You can manage the scheduling of environment updates from the Dynamics 365 Business Central admin center.
