Generally, this is a browser issue and occurs due to two reasons,
- This issue might be happening because of third-party cookies. If we enable cookies under ￼safari (or any other browser) > preferences > Allow all cookies￼, this may resolve the issue. OR
- In the Privacy setting "Prevent cross-site tracking" setting is enabled which is causing this issue. In this case, please ask them to disable this setting and test it on their end. (This setting can only be found in the Safari browser).
Please ensure that "Prevent cross-site tracking" and "Block all cookies" settings is disabled and this should resolve the issue with the website login.
