The British antitrust watchdog revealed on Thursday that it would thoroughly investigate Adobe’s $20 billion offer for the online creative platform Figma.

The Competition and Markets Authority reported late last month that it had detected issues in the supply of screen design software, where the companies compete, and found that the acquisition could result in fewer choices for creators of digital apps, websites, and other items.

It had given Adobe five business days to offer solutions to its problems. However, the American company informed the CMA on July 7 that it would not provide any remedies, the CMA reported on Thursday.

“We look forward to establishing these facts in the next phase of the process and successfully completing the transaction,” an Adobe spokesperson said.

An enquiry team made up of independent specialists conducts the CMA’s phase two, or in-depth, investigation. The CMA has until December 27 to wrap up its inquiry.

The web-based design and brainstorming platform from Figma is incredibly well-liked by digital companies like Airbnb and Zoom Video Communications.

By August 7th, EU antitrust officials will decide whether to approve the deal.
