Today I got quite lost. (I have no sense of direction) So thinking I could use google maps as a sat nav to get me home, I pulled over and tried it. Every time I press the 'start' button to get going, it reverted to my home screen on my Huawei P smart 2020 phone.
I have deleted the map app, and re installed it with the same thing happening.
If anyone has any ideas how to put it right I would be grateful.
Yes, I did find my way home, eventually.
Sorry, can't help...I tend not to rely on modern technology without some sort of back-up. (For example, there's always a large scale road atlas on the back seat of the car!...of course, you need to be able to map-read!).
You should have a car icon at the bottom of the screen with 'go'. If you had tapped on that when you were lost you should have seen 'home' at the top of the list. Tap on that and it will navigate you
