Weird blue mark on the app

[ItsCloudyToday]

For the last couple of days, a vertical blue line has appeared on the top left of my screen while using the app. There’s also one random letter “K” within the mark. My app is up to date. Not sure if anyone else is having the same happen?

Hi @ItsCloudyToday,

Thanks for flagging this. We're going to take a look into it, but would you mind sending us a screenshot?

Could you also let us know whether you're seeing this on every screen or only on certain ones, such as when viewing a thread or active?

Finally, does it appear as soon as you open the app, or only after you've taken a particular action?

Thanks so much for your help!
