My app is to let users post their items. If someone is interested, they can link to another screen to see the item info and send message to ask questions.
My problem is, when a user click the button from the item info page, it creates conversation list and link to message screen. However, if the user go back to the same item info page and click the button again, it creates a new conversation.
Are there any ways to check existing conversation before it creates a new conversation? Or are there any way to let users link to the same conversation either they enter from the item info page or the conversation list?
