Why are cookies being blocked?

Cookies blocked after changing hosting providers

If you've recently migrated your website to another hosting provider, while the domain stayed the same, existing cookies might no longer work with your new site. If fix number one didn't work, then try clearing your cookies and site data for your browser.

Why are browser cookies going away?

Google is currently set to phase out third-party cookies in Chrome by 2024. This comes after a few delays, primarily because Google wanted marketers to have more time to adjust their advertising approach and test out new, less intrusive targeted advertising technologies.

What happens to cookies when browser is closed?

By default, the cookie is destroyed when the current browser window is closed, but it can be made to persist for a length of time after the page is closed. Some cookies are 'session cookies', which means they only exist when your browser is open and are automatically deleted when you close your browser or quit the app.

Why are all websites asking about cookies now?

Websites have become more focused on asking you to accept cookies. The reason reflects a data privacy protection law that governs online data tracking and transparency. This data privacy law is known as the European General Data Protection Regulation (GDPR), which became enforceable in May 2018.
