I just saw that I had my settings set to not show me online. I do not recall seeing that before but I have had it set to offline for who knows how long.
The same thing happened to me. I noticed it a few days ago.
Your image shows you are online not off. It shows your “online status” as “green”. The drop down menu to the right gives you the option to go offline for a certain amount of time. If you were offline it would look like this.
I took that picture after I set it to online but thanks.
I’ve had that happen once when I changed some other setting (notifications or whatever), luckily, in that case, I noticed right away.
Since then, I assume it’s good to check this if you change whatever setting, at least (perhaps also if the app updates, if you use a different browser, if a windows update happens and logs you out everywhere, or just generally once a month or week, who knows, … I don’t do, though, but that slider simply setting itself to offline when I changed an unrelated setting made me wary).
