The following issues are known to exist in this release.
Subscription propagation between members of a StoreFront Server group fails when TLS 1.0 is disabled in Windows and Windows Server is using .NET 4.5 Framework server. By default, .NET 4.5 Framework uses TLS 1.0 only. A workaround for this issue is to upgrade .NET Framework on the server to 4.7 or later (which use TLS 1.2 by default). [STF-2413]
There is a known third-party issue with smart card authentication and Microsoft Edge. To work around this issue, use Internet Explorer. [DNA-47809]
Workspace control reconnects to only one app session instead of all the apps in the workspace. This issue is seen if using Chrome to access the Receiver for Web site. To work around this issue, click Connect on each disconnected app. [DNA-25140, DNA-22561]
