Dear Samantha:
There is a KB on this that apparently needs an update. Are your users using the same browser sessions or new ones each time? If the latter, it should go away.

After the user logs in again a new token is created and Webview will function normally. The issue can be avoided entirely if user uses a new browser session. Either way, there is no functionality loss caused by the error and it can be safely ignored. This issue is permanently addressed in APM 10.1.
Looking in Team Center is displaying blank screen with Error I see the following with DEBUG logs (Something I mentioned above as a task to do) Can you set Webview log in debug for a short time and report back any lines before the XSRF warning?
8/22/16 10:18:41.607 AM MYT [DEBUG] [WebView] CA-APM Cookie is NULL.
8/22/16 10:18:45.983 AM MYT [WARN] [WebView] Failure due to validate XSRF token.
What browser are you using? Is it HTML5 compliant?
Are you using any browser extensions/plugins which may cause the page to not render properly?
Lynn_Williams anything to add?
Thanks
Hal German
