Just some major issues

I love snapchat its a really good app. But, I have had some several issues lately. So, one day I wanted to free up some storage cause Im so sick and tired of my phone saying my storage is full. Also, snapchat is taking a lot of storage so thats the main reason why I had to free up storage. So Ill delete some apps and itll still say my storage is full than I check in my settings and snapchat is taking all my storage. So i deleted. Than once I tried downloading it back, it says on the App Store that its loading and downloading or whatever but it doesnt show on my home screen. Whats up with that? Please fix that and sometimes it has bugs where the app just crashes a lot ! PLEASE FIX THAT!! Other than that its a really fun app I recommended. It doesnt happen to a lot of people tho... but its still an amazing app!!
