nothing i do with maps works - eg downloaded maps just show a fuzzy grey area in an orange tile border. Imported all trails routes show blue in the collections but dont exist or are faint purple or grey line in maps. But when i put my phone in airline mode, and switch to offline maps only, and i go to the maps tab and the area I want to walk in, it shows all the details I need anyway. Does that mean I don't need to download any offline maps because somehow the explore app has the data anyway??
