We are aware of this issue and it was noticed on chrome and we are working on it to get is resolved asap. As a possible work around try removing the extension and re installing to check the issue status.
Also let us know if this issue is observed in multiple browsers as well.
This is also happening with FireFox. I have tried disabling and re-enabling, as well as uninstalling and reinstalling on both Chrome and Firefox, but it is still not working. Please keep me posted on the resolution, as right now TrueKey is nearly worthless for me.
