Crash and Inaccuracy of location detection

Crash constantly, and it will throw my avatar a few blocks away from my standing location at the gym spot. This happens when I was at the Times Square. Asked peer raiders, and the answer is good luck if you can get close enough to the gym. I had to literally walk around the blocks and jump in by chance. By random chance. I got so frustrated and disoriented. Spent money in the raids but not able to catch any. It should be a 5 minutes thing, but it took me half hour. Battery was totally drained and shut down when ready to battle. Worst app experience ever!!!
