A change to the Teams update policy allows tenants to connect Teams preview mode for the desktop client with Office Current Channel (Preview) for the Microsoft 365 apps for enterprise. When the change happens in late July, accounts configured to use Office Current Channel (preview) will automatically use Teams preview. It’s kind of logical because Teams is so closely connected to Office. In any case, settings are available in the Teams update policy if you want to move away from the enabled by default status favored by Microsoft.

The old AllowPreview setting is being deprecated. You therefore need to move to the new AllowPublicPreview setting if you want users to be able to switch into preview (or follow Office automatically). Here's what an updated policy looks like:
Get-CsTeamsUpdateManagementPolicy -Identity "Test Teams Users"
Identity : Tag:Test Teams Users
Description : A policy to test new Teams features before they are generally available
AllowManagedUpdates : False
AllowPreview : True
UpdateDayOfWeek : 1
UpdateTime : 18:00
UpdateTimeOfDay : 03/07/2021 18:00:00
AllowPublicPreview : Enabled
