Welcome to iMore! It sounds to me like you’re running a very old version of iOS and running into app compatibility issues. You’ll want to make sure you’re running the latest version of iOS your device supports, which I believe is iOS 9.3.5. That should help but iPhone 4s was released over six years ago so you’re likely to run into issues regardless.
If you have any further questions please join the forum and reply back in this thread.

4s

Clearly that’s what I meant considering iPhone 6s runs iOS 11 and wasn’t released 6 years ago. Regardless, my answer is the same.
