Starbucks Corp.’s mobile ordering via its app appeared to be down on Tuesday morning.

About 1,400 users reported issues around 9 a.m. in New York, according to Downdetector. Attempts at mobile ordering by users in Chicago, New York and Atlanta showed a “system error” around that time. The company didn’t immediately respond to requests for comment.

The chain had planned a buy one, get one free deal from noon to 6 p.m. on Tuesday, according to a promotional email sent to rewards members. Starbucks has been offering discounts more frequently to spark demand following a sharp pullback earlier this year.

Starbucks reports results for its fiscal third quarter on Tuesday. The chain is under increased scrutiny to improve results after an activist took a sizable stake, according to the Wall Street Journal.
