Glo Slow Page Turn

I started reading off my glo again last week and gradually over the last week the page turn has gotten worse and worse.

I did a factory reset to wipe it clean and it's updated with the latest firmware. I have tried a few times to do a quick reset but that hasn't helped. I'm up to my 3rd book, so I don't think it is the books.

Is there anything I can do to stop my glo from being so sluggish?
