Tesco Clubcard has issued a major warning to its customers to act ‘within days’ ahead of a big change to its app.
Shoppers could miss out on bargain buys and Clubcard benefits as the app will not work after March 31 unless they update it, the retailer said.
The change will affect millions of customers who rely on the digital version of the loyalty app.
The supermarket giant is also wary of potential security concerns and data breaches as it makes the change.
In an email to customers, Tesco said: ‘To increase your data protection and online security, we’re updating our Tesco app to a newer version.
‘After March 31, older versions of the app will no longer work.
‘To keep shopping and enjoying all of your Clubcard benefits on your app, make sure you have the latest version before March 31.’
Tesco said the behind-the-scenes update won’t affect its website Tesco.com.
Shoppers can update their Tesco grocery and Clubcard apps via the Apple App Store or Google Play.
It comes after the retailer axed the popular Tesco Pay+ feature from the app just weeks ago.
It means shoppers can no longer pay for their items and collect Clubcard points in one swipe at the checkout.
A spokesperson for Tesco said the supermarket regularly reviewed the payment options available to shoppers.
