If you are able to sign in and have been able to clock in before, but now TSheets is non-reactive, there are a few things that could be causing this problem.
If that doesn't work, check your browser for add-ons that may have been installed for extra privacy protection or extra security protection, as there are a few browser add-ons that we've seen cause this problem.
Once you've adjusted your security settings, removed any superfluous browser add-ons, and you're still having browser trouble, chances are you may just need to try a different browser. Get the latest version of another browser or two, and try to clock in.
If even using a different browser doesn't solve the problem, contact our support team. We are happy to walk you through some bug reporting options.
