XTM users working in the Google Chrome browser may experience issues with:
opening Workbench for subcontracted projects;
switching between accounts in TM and Terminology manage tabs;
opening XTM pages inside external systems.
This is caused by a recent update to the Chrome's cookies policy (known as SameSite). In order to work around this issue, please, switch to Chrome's previous behavior by adhering to the following steps:
Go to chrome://flags/#same-site-by-default-cookies → SameSite by default cookies;
Choose Disabled;
Relaunch the browser.
