October 17th.

Tesco have told us that users with password of 10 characters or more will fail to login due to a ‘bug’ with their shopping servers.

This is NOT a bug in the application.

If you have a password of 10 characters or more you will have to login via Tesco.com and change to a shorter password to use our application. Over length passwords will generate a login error “Error 200”.
