Have you noticed missing Fonts on the https://webapp.lifesizecloud.com page using Internet Explorer 11. This issue can occur when Internet Explorer's security settings prevent web fonts from downloading.
You would see this problem on the default logged-in page of https://webapp.lifesizecloud.com
This problem can be fixed by adjusting Internet Explorer's security settings to enable font download, which will allow your browser to display web fonts.
To enable font download in Internet Explorer 11
Open IE settings (the cog or gear icon) in the top right corner of the browser.
Click Internet Options.
Select the Security tab.
Click Custom Level.
Locate the Font Download option and set it to Enable.
If your entire company is experiencing this issue, then preventing fonts from downloading may be a security policy defined by your IT department. To resolve the issue request your IT department enable the Font download setting in Internet Explorer for your organization.
If your organisation has security concerns enabling this setting globally for all applications, they should be able to allow it exclusively for lifesizecloud by adding webapp.lifesizecloud.com as a trusted domain.
