Software fixes take time:
1. Find the issue in a highly reproducible way under lab conditions
2. Try a fix
3. Test (this is often a much longer process than the fix itself)
4. Distribute the new version (this can also take time since M doesn't have 100% control of the mechanism)

We'll be seeing fixes in apps for a long time. It's only been 6 weeks since iOS 8 was released. I'd guess if they've been really working at it, they're somewhere in the cycle between steps 2 and 3 (above).
