Restart your phone then start it again

I have heard lots of complaints about this.
I would just delete the application, re-install it and restart your phone. If that doesn't work, I would try disconnecting from your Wifi, then re-connecting.

At this time instagram is having difficulties lots of difficulties. Most concerning using subscribers images without their approval. They sell users images without compensating the original image creator.

I'm finding it hard to open an account on instagram why, please help

My Instagram won't open and I can't restart my phone because my lock button is jammed. I've already tried deleting it and installing it again it still doesn't work.
