I seem to appear online on facebook chat 24/7 and there is a little mobile icon next to my picture in chat box. I’ve removed my number from the site and deactivated mobile notifications via text messages but I’m still on chat all the time.
How to fix it?
Thanks in advance.

Ye I had the same problem and I just deactivated and reactivated my account again and it took the icon beside my profile away, hope it helps.
