I am new with dash I am developing a multipage app. In one of the pages I have a Dropdown and Datepicker connected to a table and everytime I am selecting something a new tab in the browser is opened with the updated table. I assume that this behaviour is related to the debug mode.
I would like to show development of the app to my team without the app always refreshing and opening a new tab. Therefore I am trying to run the app with the debug= false but if I try to do so I get the following message:
Dash is running on http://127.0.0.1:8050/
