Why can't i see gps metadata from someone's else photo?

I read about this in Mark Goodman's book:"Future Crimes" and i wanted to try if this actually works. It doesn't for me. I tried
my iPhone photos (even turned on location accesses for camera) and i just can't see gps coordinates.
Do you maybe know what is the problem?

Which is better, The iPhone 6s or iPhone 6s+?

I'm a 16 year old girl and am 5 4" so am rather short for my age. I have the choice of using my mums old iPhone 6s (with 12GB) or my step fathers old iPhone 6s+ (with 32GB). Both are broken so I have the choice of fixing one of them. For my size would the 6s+ be too large?

Should I give up on my career?

I'm 19 currently in community college getting my associates degree and then I wanted to transfer to a university to study cinematic directing. I'm barely in my second semester of college but I don't have a lot of money or even a good job to pay a university and it doesn't look like I can get a scholarship, my grades are good but not good enough to get a good scholarship for a good university which is pretty much what I need given that the film program is their most expensive. That is now my only issue, I'm starting to lose hope in myself. My cousins are always annoying me about how I don't make videos or movies or anything to show I have a passion for it. I don't have a camera or money to get a good camera, or actors. For my high school senior project I made a 7 minute film with a schooled borrowed (terrible) camera and with my cousins as my actors (terrible). They say just use your iPhone camera, which isn't too bad of an idea… If I had actors. Plus with my job and school I don't really have time. Then there's my little cousin, he is 11, he started a YouTube channel, which is growing fast, and he's making skits and vlogs and all this stuff. My point is that this 11 year old could accomplish what I can pretty much only dream of. How? Because if he becomes a good YouTuber he can start to make real money, get noticed, and probably get a job in a series or a movie of some sort like the more popular YouTubers have done, and trust me he can do it.

What happens when you send an iMessage to someone who has an iPhone, the messages show that it was delivered, but then it shows nothing?

I was sending messages to my friend through my iPhone, it showed that it was "delivered" each time, and then out of nowhere I sent a few more and it showed nothing? I can't tell whether the remaining few messages were sent or not. Does that mean I was blocked? Is there a problem with the cellular data on my end or on my friend's end? Was my friend's phone not on? What could it be and how can I tell?
