New York (CNN Business) Taco Bell has a tortilla problem.

The chain said that some restaurants are experiencing supplier shortages of tortillas, and that it is "working diligently to replenish the supply." Taco Bell , which has about 7,000 locations in the United States, did not share how many restaurants are dealing with shortages.

"We apologize for any inconvenience this might cause," Taco Bell added in a statement. The tortillas are used for its quesadillas and burritos.

Some exasperated social media users complained about the limited menu on Twitter.

"I am at one of your Greater Rochester area locations and they are out of tortillas!" One user wrote on July 1. Another user complained on June 30 of shortages at a location in Rome, New York. A number said they were told by staff that the Taco Bell shortage is happening at locations nationwide.

Taco Bell did not specify which or how many locations are affected by the tortilla shortages.
