The Tesco API has been experiencing some problems lately. On around 26th October its SSL certificate expired. They fixed this last week but anonymous login was broken. Anonymous login allows Paperless List to access data on Tesco products for sale without the need for a tesco.com account. I learned today from the Tesco Labs team on Twitter that anonymous login has been disabled because it was being abused (not by me but presumably other app developers). This means most of the functionality of Paperless List doesn’t work so I removed it from the Google Play Store. Existing users can still use the app but it will only work with manually added (i.e. not Tesco) products. It’s a shame because I have been working on a material design update for the app for a while. It looks like this:
Paperless List may be resurrected with a login screen in order for it to work again with the Tesco API.
Edit: Tesco have a new API with anonymous login but it has less features. I am exploring the possibility of using it and keeping tabs on its development
