If so: try another browser. If it’s happening on mobile, see if that’s also the case on a desktop or tablet. The most likely culprit is a cookie issue, in which case clearing your cache/cookies and double checking your browser settings could resolve it.
Yeah, it sounds like a cookie issue. It was the only such report we had.
Sometimes cookies can be corrupted for various reasons, or browsers can be set to disallow them, which can cause problems including with logging in or staying logged in.
I’m glad to hear that you haven’t encountered it since reporting the issue.
