VCF Automation9.0.x versions prior to 9.1
This issue is caused by a problem with session token renewal. Even if other tabs are active, an idle tab will still attempt to refresh the token, which forces all open tabs to refresh as well.
Fixed in release 9.1 and higher. See Download Broadcom products and software for steps to download this release.
In version 9.1, the product is fixed as it no longer uses local storage to maintain access tokens across browser tabs.
Each browser tab now maintains its own access token in memory and relies on an HttpOnly cookie to retrieve the same user session from the backend across browser tabs.
