Just tried with Microsoft Edge and Firefox. Works fine as expected.
On the other hand, fail to log in the app with all the other web browsers I've got: Chromium, Opera, Vivaldi...
Perhaps some privacy settings need to to be changed?

If I log in windy.com as in the past, I'm directed to the forum and unable to get to the actual web app. And if from there I go to the app (entering windy.com), I'm not logged in any longer. That's with Opera and Win 10.
What should I do to log in straight into the web site (the weather app)?
Thanks,
Alex

Worldwide tides here. I believe xtide is "inspired" by wxtide. The displayed output looks the same.
Cheers,
