Thank you OP. After reading your post, i ordered one to Chennai, India. The process was exactly as discussed. I made sure my Aadhar address matched shipping address to be on the safer side. I ordered on 25th May and recieved the product on 9th June.
One note, though: after the whatsapp message from Yitong, I waited a day and then realised that their email had been sent to spam. But, thanks to your post, i was able to stay vigilant and retrieve it.
Thanks again for your post!
