No support for iOS < 9 in Dropbox V2 API for Objective-C???

iOS 11, 10, and 9 are backward compatible to V1, aren't they? if not, why not have more than one version of your client so you can stay compatible. Why inconveniencing so many people and potentially lose these customers? You might ask why not upgrade to iOS 9? The answer to that is Apple no longer provide iOS 9 and iOS 10 crashes older phones like the iPhone 4s which is still currently being resold on the market by mainstream phone vendors. Why risk crashing a phone, I tried the upgrade on my iPhone 5 and it bricked it. Apple won't resolve the issue. It is beneficial for Apple to force people to upgrade their hardware for profit, not to the end-user. Environmentally keeping older iPhones active with Dropbox is beneficial to a lot of people who use them in their everyday businesses. There are still millions of iPhone 4S in service to this day and much more for sale. iOS upgrade and those older model phones are guaranteed to break most of them. 

There are over 30 million plus iOS 8 users that no longer have access to Dropbox. There are over 20,000,000 other IOS users below IOS 9. Why would Dropbox want to inconvenience 50 Million plus customers? Not a good business practice. Were they paid off by Apple to do this? Not saying they were, but something is very suspicious here. Having a backward compatible app makes a lot of sense. 

To the CEO of Dropbox, do you care about your users? Just think of all those older IOS, OS X and Windows devices out there. This is a large avenue of current and potentially new customers. Think about this, you won't regret it.

Thanks for the detailed feedback Hank66! I'm sending this along to the team.

If you add the number of IOS 9.3 users who now are not able to downlaod Dropbox, that is a staggering number of users. Why don't developers realise that a lot of users are not going to update to the latest release if they are happy with what they are using!
