How to upload cover photo on Facebook app for iPhone?

There was a new update yesterday, August 23rd, and it happened to change the option to upload a cover photo via Facebook app. Now it won't show the option! I want to upload a picture from my camera roll on my iPhone. Can I still do that? If so, please explain thoroughly, please and thank you.

Step 1. Open the Facebook App
Step 2. Once your Facebook app is open, click on Profilie.
Step 3. This will take you to your profile page. Click the carmera icon on the left of your screen.
At this point it is up to you. Do you want to upload a picture you have already taken, or do you want to take one?
If you select 'Choose from Library' you'll be taken to a listing of your photos where you can choose a photo to upload.
If you select to 'take a photo now' to upload, the camera function will be enabled and you can take (and retake) your photo then tap 'Use Photo.'
Once you select a photo you'll have the chance to write a caption (or not).Tap the 'Upload' button and the photo will be posted to your Facebook wall and automatically added to a 'Mobile Uploads' album on your Facebook 'Photos' tab.

That's it. Now you can upload mobile photos to Facebook, no matter where you are, using your iPhone. In my next note I will cover uploading to a specific album, like My Garden, friends, or whatever album you choose.
Until next time…

As you login in to Facebook tap over your name to view your profile.
It shows your profile pic and the cover photo with camera symbol to the right side. Tap over it and change the cover photo by choosing from the existing album or capturing from the camera or selecting from camera roll.

Hope this works.
