The settings menu is at the bottom left of your screen, indicated with a cog icon.

Once you click on this a new page will open (as below). If you have a group of settings, and you have access to all of these, you can navigate to each setting using the drop-down menu.

You can also access your personal account settings from here, using the My account button on the top right.

The settings menu is where you can find the option to make changes to some of the most basic functions in the app.

To edit information in the settings menu, you'll need the 'Edit opening hours, info etc.' permission enabled.
