@Thomas669 And then what do you do when you are on the community page? If you haven't already, when you are on the community, click on your profile photo in the top right, click on Log-out. It will then take you to the main airbnb page with a "log out" in red at the top of the page. Sometimes on that page, my hosting bar is visible, and I'm already logged in to my hosting account, sometimes it's just the generic heading (don't ask me why it varies, another of Airbnb's tech mysteries). If your hosting bar is visble, don't log out, just click on anything there you want to access. If it's not visible, go again to your profile photo on that page, and click on Log-in.
And clear your cache before doing any of that.
And you say you keep trying browser links- don't. They are obviously not working for you.
