Any news about this topic? I’m desperate…my Vaadin pages inside iFrame always report “Cookies disabled. This application requires cookies to function. Please enable cookies in your browser and click here or press ESC to try again” error.
I tried many “solutions” (like sameSiteCookies=None into Tomcat’s context.xml) but none worked.
Using TomCat 9, Vaadin-core 14.2.0, Chrome (only in Chrome I got this error).
Please let me know if you are able to discover the original cause. Also, if there’s any information missing in the walkthrough, just let me know and I’ll update it.
