Your browser can work well for a long time without needing an update. However, as it becomes outdated, more and more websites may stop working properly.
Websites like Eitje stop working in older browser versions because web technology constantly evolves. Browsers need to keep up with these changes to display websites correctly and support all their features.
For example, Eitje does not support Safari version 14 (2020) or earlier.
If you try to open web.eitje.app using one of these versions, you’ll see a notification explaining the issue.
Updating Safari to the latest version should allow you to log in again.
