I would NOT take it as a sign there is something wrong with your phone.
You can try rebooting your phone (did you turn it off and on again?)
You can also check to see that there is a few gigabytes of free space on your phone as once in a while I get the "Dad, it's not working!!!" and they filled up the phone storage.
I have 2 updates on facebook and another game app in my iPhone 6 since like a week now. pic won't load but it seems like they are loading endlessly. it is not updating.
So is there a way to fix this or remove these updates?
