The music streaming app Tidal is laying off more workers. In a statement to Fortune, an unnamed Tidal spokesperson confirmed “the elimination of some roles across our business and design teams.”

On Wednesday, Fortune published a leaked memo from Jack Dorsey, the CEO of Tidal parent company Block Block Head, who said that the company is going to “part ways with a number of folks” on the team. “We’re reducing the size of our design team and foundational roles supporting TIDAL, and we will consider reducing engineering over the next few weeks as we have more clarity around leadership going forward,” Dorsey wrote, according to Fortune.

Though Dorsey’s message didn’t specify how many employees would be laid off, sources told Fortune that it could be around 100 employees — or about a quarter of Tidal’s remaining staff. Tidal cut 10 percent of its workers last December, and Dorsey reportedly considered a major reorganization at Block in July.

Earlier this year, Tidal merged its two high-fidelity music plans into one $10.99 / month subscription, lowering the price of its most expensive plan as a result. It also made FLAC the default audio format for stereo, while adding Dolby Atmos for immersive sound.
