Is anyone using the Chat function in Atera?

I was wondering if there are people who use the chat function in Atera? I find it to be a nice feature and would like to use it to chat with customers and vice versa. Unfortunately, our experiences have not been good, and we have never really gotten it to work. Hence, I'm curious about others' experiences. When we try the function, we often encounter a timeout, or it only works one way, or nothing happens at all. We have opened multiple tickets on this issue. The engineer then creates the ideal conditions. Clearing browsers on both ends, deleting site data on both ends, ensuring the use of Chrome instead of Edge or Firefox. Deactivating and reactivating the chat, etc. This way, the ideal lab conditions are created each time, and then voila, it works! However, the first time we try it in a 'real' environment, it naturally doesn't work again. Calling the customer to create ideal conditions for starting a chat is not realistic. I understand that it is browser-dependent, but whether it is workable in this way is questionable. I am really curious if there are people who can use it without issues.
