I am having this issue on my on-premise database where order updates from PoS dont get updated real time on the kitchen display. I have to manually refresh the kitchen display's browser tab to get updates. 

I noticed it does not happen over http only https. I also noticed there is no issue with it on odoo online or odoo sh. Only on-premise deployment. It has been an issue since v17 and I had hoped it would get fixed it v18 but the issue is the same. I have contacted technical support but they give me generic answers like "install latest version of odoo". I have reinstalled multiple times. One other person said I should install a browser plugin that refreshes the page after regular intervals. 

Is there anyone with this issue or that is using kitchen display on-premise?
