The Telegram field in the Social Networks section of Profile doesn't specify what format you want the link in. I had it as https://telegram.me/[username] but you were changing it to https://telegram.me/https://telegram.me/[username]/[username.me] when the user taps it, so nobody was able to message me. You should detect if the user has input their Telegram link, just their username, their username with the @ symbol or their phone number instead of assuming one of those things and providing the wrong link 3/4 of the time.
