I am a heavy Smartsheet user. On a normal day, I have over 50 browser tabs open, each with their own Smartsheet. I use Chrome and have them grouped in Chrome tab groups. I have been using Smartsheet like this for years. In the past couple of months, I have seen a major bug. The tabs will occasionally log out. This is normal. What is not normal is that when I click the button to log back in, a bunch of the tabs will all open to the same Smartsheet. They each had a different Smartsheet loaded before they logged out, but when logging back in, they all load the same page.
This began after the new login system was released by Smartsheet, which makes me wonder if this is related to that change.
