Each time i try to upload my profile on facebook
There could be couple of possibilities.
1. Your app is outdated and you need to update it.
2. Pic is changed but some how due to network problem, your app is unable to return a success message. You need to check your profile on desktop or laptop to be sure that changes you wanted have been made or not.
3. Check your network connection (signals) may be due to network coverage problem, you are unable to upload your pic.
