Be careful — there are no warnings on the service's website! If you add test channels to Umnico and connect their widget to AmoCRM, it will be impossible to delete the test channels. They will keep appearing in all deals and contacts, regardless of their number. Even if you remove the widget and the channels themselves in Umnico. Other issues that the platform does not mention can only be guessed at. There is no trust in it; it is unreliable. I do not recommend it. Support does not respond at all, as if it doesn't exist.
