Known issues in StoreFront 1912
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]
When StoreFront is installed on Windows Server 2012 R2, it may fail to register with the Citrix Analytics service (CAS). This happens when the C++ run time software components are not already installed. The StoreFront stand-alone installer does not install these components. A simple work around is to install C++ run time before or after StoreFront is installed. [WSP-4412]
