In order to boost its mobile app subscriptions, Taco Bell offered a free Chalupa Cravings Box.

Fans can grab the offer by downloading the app and placing their orders. However, many consumers had to face a technical issue while doing so.

Taco Bell fans were asked to redeem a free Chalupa Cravings Box that includes a 5-Layer Burrito, taco, cinnamon twists, and a drink after downloading the app. There were asked to sign up until June 30 to redeem the offer.

After ordering, use must go to their nearest participating Taco Bell drive-thru for contactless pickup.

However, customers reported technical glitches and crash in the app as they were trying to register to redeem the offer.

One consumer shared a screenshot of Taco Bell’s website, saying it was experiencing higher traffic than usual.

Many fast-food chains and restaurants have been trying to boosting their mobile app subscription to offer customers contactless options. Last week, Chipotle launched Pepper, a new Concierge Bot on Facebook Messenger so consumers can place mobile orders.

On June 18, Taco Bell said it does not prohibit its employees from wearing Black Lives Matter masks.

The fast-food chain said it was working closely with its Ohio franchise after a former employee said he was fired for wearing a mask, supporting the movement.

On June 8, Denzel Skinner shared a live video on Facebook about getting fired from its Ohio franchise for refusing to take off a Black Lives Matter mask.

Taco Bell told USA Today, “We believe Black Lives Matter. We were disappointed to learn about the incident that took place in Youngstown, OH. We take this very seriously; we have been working closely with our franchisee that operates this location to address the issue.” The fast-food chain said it had spoken with Skinner to “apologize and discuss the situation.”
