Hi and thanks for your feedback! Indeed, I noticed this 2 days ago as well. It looked like the pocket service was returning an error when I was reaching it, but I had no more information. It's back to normal since then, and I'm contacting pocket to know if they have a clue about what happened. You should now be able to load your pocket items as usual. Sorry for the inconvenience.

2018.05.04 update : got an answer from Pocket and the issue was indeed on their side ;)
