When registering your License Server with Citrix Cloud, the Citrix Licensing Manager UI might stick and display a spinning wheel. To avoid this issue, before registering your License Server with Citrix Cloud, ensure that you have the Digicert Global Root CA certificates installed in the system. These certificates are updated in the Windows update. If they’re not installed, manually download and install the certificates before starting the Citrix Cloud registration. Also, ensure you verify firewall settings. For more information, see the Important note under Register and remove registration with Citrix Cloud. [LIC-1510]

When used with concurrent licenses, the License server build 31000 is not backward compatible with the Citrix Virtual Apps (previously, XenApp) 6.5 and earlier version. It is recommended to use License server v11.16.6 build 30000.[LIC-2807]
License file issues
The License Server ignores license files that have multiple lines referencing
HOSTNAME=.Licenses in these files cannot be checked out. This issue is caused when you download licenses associated to different License Server host names in to the same license file.
To resolve this issue, download again separate license files for each Citrix product tied to different License Server names.
Licenses with expiry dates incorrectly formatted as
D-MMM-YYYYappear as permanent in Studio. Use the Citrix Licensing Manager to display the correct license expiration dates. [LIC-2556]
