Is ChitChat down or is it me?
Usually it is something on your device, and it takes under a minute to find out. Open any other website. If that loads slowly too, the trouble is your connection. If other sites are fine, reload ChitChat once, then try it in a second browser.
If it works in the second browser, the first one has a stale session or a blocked permission, and the sections below will sort it. If the site will not open anywhere, on Wi-Fi and on mobile data alike, the problem may be on our side. Wait a few minutes and try again before changing any settings.
