Both dash board and the app shows 62 miles - 100% charged.
Driving an EV can have a steep learning curve. There is nothing wrong with your car. Rest assured your battery is charging to 100%. You can verify this on the energy screen in the car, accessed through the button with a "leaf" on it. Also, charging at Level 1 or Level 2 makes no difference to the level of charge the ultimately achievable range of the car on the full battery.
All that's happened is that you're driving to aggressively and/or too fast. The 62 miles is only your currently
estimated range and
depends entirely on your driving style (again, it does not indicate the level of battery charge, just what the car "thinks" you can do with that charge). The car had likely been driven more conservatively before you picked it up from the dealer, and thus was estimating 75 miles on a full charge. But, you've been having a little too much fun since then (driving fast? accelerating hard?).
Try driving the car more conservatively for a while. Your range estimate should start to increase.
In order for a range estimate in the 70s, you need to drive using an average of around 250 Wh/mi. You can see your average Wh/mi using the trip meter accessed via the left-hand dash display. I suggest you reset the meter (by holding the left OK button on the steering while) to start a "fresh" average (for display purposes only; this reset does not affect the range estimate) and then drive around. Practice your driving technique until you can consistently average about 250 Wh/mi, and you should start seeing range estimates like 75. Also in the left-hand dash display, the Brake Coach and Energy View may help with cultivating a "good EV driving style".
I suspect your current average Wh/mi is around or above 300, which would explain why your range estimate is in the 60s. On the other hand, if you can average near 200 Wh/mi, you should see estimates in the 80s, and even 90s. ('Course, you actually have to maintain that low level of energy use to actually achieve those ranges.)
Also, turning on the climate controls (especially heat, which consumes a lot of energy from the high-voltage battery) can also significantly affect the range estimate, and can take
tens of miles off it. Try curtailing use or turning off the climate controls.
One final reality check: Speed and heat are range killers. In order to get 75 miles of range, you need drive "well" and keep speeds no higher than 60-65 mph, probably with climate off or mostly off. If you're driving around at 70-80 mph everywhere, and blasting the heat all the time, you simply won't achieve anything like 75 miles of range.
