Before, I do not know, we have developed a bot, now we think how to promote it. I have not faced with promoting channels and bots in Vyber before, so I do not know.
There is a link from the platform on which the bot was made, but in this version of the transition to the application passes through the padding "Join"
Advertising only on phones, but the standard link through the share does not work with the PC that with the phone with the installed application.
Thank you for your reply.
