I switched to pool settings today for an outdoor lido swim. When I looked down at the watch it seems to have gone into some kind of back menu and I can't find anyway out of it. I can move around the menus but it's not the normal display or user menu, more like factory coding or similar. All online reboot suggestions involve rebooting from the setting menu on the standard display which this isn't. Can anyone help me switch it 'on and off' again, and more importantly tell me what did I do to access this 'back' menu. Thanks in advance...
