Users who are experiencing login issues after upgrading to version 7.7 or above.

No elevated permissions are required.

This article explains why login issues may occur after upgrading to version 7.7 or above and how to resolve them.

1. Background

In late 2019 and early 2020, internet standards required cookies from other sites to be marked SameSite=True and Secure. System updates were made to maintain login validity.

A 2025 proposal introduces Cookies Having Independent Partitioned State (CHIPS). More details: Cookies Having Independent Partitioned State (CHIPS) | Privacy Sandbox

To prepare, partitioned cookies were added in version 7.7. Though rollout may be delayed, modern browsers already support this.

2. Challenges

When users first upgrade to a version that uses partitioned cookies, the browser stores a new partitioned cookie at login. However, the browser may also retain the older non‑partitioned cookie.

When the system checks for the login cookie, it may detect both versions stored for the same site. This causes confusion and can invalidate the login session.

As a result, users may be repeatedly logged out or stuck in a loop where they cannot complete the login process.

3. Identifying the issue

Stop the page loading while it is on the site address, then press F12 to open the browser’s developer tools.

These steps use Microsoft Edge as an example, but the process is similar in Chrome and other browsers.

Select the three dots in the developer tools window and choose the first icon next to Dock location to open the tools in a separate window.

Select the Application tab, expand Cookies, and then select the hostname for the site.

The list should show only one of each cookie. If you see more than one entry for items such as .TARA.AUTH, this indicates that both the old non‑partitioned cookie and the new partitioned cookie are being stored.

4. Solution

4.1. One site

If you have identified duplicate cookies, select each cookie in the list and press the Delete key to remove them.

4.2. All sites

You can also clear all browser cookies. This is easier but will sign you out of other websites. Clearing cookies and other data may also remove cached content.

Flight mode stores data in the browser cache, so you must not clear the cache while documents are stored in flight mode. You should also avoid updating the system while documents are stored in flight mode, as version changes may prevent documents from being checked back in. Documents should not be stored in flight mode during an upgrade.

4.3. Targeted fix for many users

Companies may choose to script a targeted fix that clears cookies for the specific hostname across all users’ browsers. This would need to be handled by the company’s IT department, as it is outside the scope of support.

5. Could this happen again

This specific issue will not occur again, as the change has already been implemented. Future internet standards may require further cookie updates, but once users are on a version that uses partitioned cookies and the old cookies have been removed, the login process should continue to work without needing to repeat these steps.
