When I try to view it I click on begin messaging on Telegram Desktop but then it comes up with a QR code to start the sign-up process.
I'm on a Desktop! I'm not going to use my cellphone to watch this. These people are idiots for designing thear platform this way.
The content is only a text message, it should appear.
I never provide phone number i’m not comfortable with it.
