If it is at the beginning of the sentence "Lei" can mean both "She" and "You" (formal). I hope you reported it.
I didn't see a way to report this, only this discussion option. Next time I'll look for a way to report an error. Thanks.
I can't report from my phone app, only from the computer. Maybe that's why you can't report too.
This is a very old comment from when I was doing the Strengthening exercises (or whatever they are called) and I didn't know they hadn't introduced the formal Lei. And perhaps I wasn't aware of the reporting procedures. I work only on a computer.
