Try this quick checklist first
If something on the Cosmos platform is not working as expected, working through this checklist solves the problem in most cases. It only takes a couple of minutes, and it usually saves time on both sides.
Step 1: refresh the page
A surprising number of problems are solved by a hard refresh. Hold Shift while clicking refresh, or press Ctrl+Shift+R (Command+Shift+R on a Mac). That reloads the page from scratch rather than from your browser's cache.
Step 2: try a private or incognito window
Open the Cosmos platform in a private or incognito window. If it works there, the problem is almost certainly something cached or stored in your normal browser session, which you can clear in the next step.
Step 3: clear your browser's cache and cookies for the site
Browsers store data to make sites load faster. Occasionally that stored data gets out of date and breaks something. Clear the cache and cookies for cosmos.global, then sign back in.
Step 4: try a different browser or device
If it still does not work, try a different browser entirely, or a different device. If it works on one and not the other, the problem is local to the first; if it works on neither, the problem is on our side.
Step 5: check your internet connection
If pages load slowly or things seem half-broken, your connection may be the cause. Reload another site to compare, or switch networks if you can.
Step 6: tell us
If none of the above has fixed it, tell the team. Send a quick message with what you were trying to do, what happened instead, and what you have already tried. A screenshot is enormously helpful. See Reporting a problem to Cosmos for what to include.
