Why all the bugs?

Seems like I need to restart the app 3-4 times a day because it bugs out and something happens like it cant find the GPS signal all of the sudden. And of course it always happens at the times that you least want it to happen. Been a consistent thing since day 1, I guess they dont have much time to focus on ironing out some of these bugs, even 9 months in? Also, nanab berries are next to useless... just another item to fill up the bag so that users feel more compelled to buy more bag space? No thanks, Ill simply be emptying my bag of them every time I get some.
