Thanks for reporting this. Since this isn't a global issue (all users) it's specific to possibly a browser, an addon to the browser, a type of device, etc. etc. etc.
So, we'll need to find a way to duplicate the issue in a repeatable way to try and fix it. That being the case, the peeps that have it happen to them need to reply with answers to these questions:
• Are you on a computer, tablet, phone.
• If phone / mobile, which model? If computer, which operating system and version?
• Which browser and version are you using (eg., Chrome 58.0.3029, Firefox 3.5.9, Internet Explorer 8, etc.)
• Have you tested a different browser (this helps us isolate if the problem is browser related or not)?
• What EXACTLY did you do? Document the steps you took before having the problem.
So, once we find commonalities between who it is and isn't happening to, we can try to duplicate the problem on our end and fix it.
