Gentlemen, help solve the problem. First, some information. VKontakte groups have the ability to activate the reception of messages, as well as write text. This text will be sent to users who open a dialogue with the group for the first time. I receive messages when I enter this dialog through a browser.
Now about the code. In my application through the API, I send a message to the group (the messages.send method). The message is sent and it turns out, this is no problem. The problem is that the reply message entered earlier from the group does not come back. How to fix the situation?
Surely there is such an opportunity. I use the mobile client application for this social network (Kate mobile). If I switch to a dialogue, I see my sent (via API) message and immediately receive a response from the group. Also with the web version.
