Online payment processing service Paypal is ditching support for several mobile platforms.

The online payment platform recently announced that it is pulling their apps from operating systems Windows Phone, Amazon, and Blackberry starting June 30, 2016.

In a statement, Paypal said its decision to remove its mobile app from select platforms will help its developers focus more on iOS and Android. Windows Phone and Blackberry have never been a big mobile market for the online payment site, but abandoning Amazon’s Fire OS could cost Paypal given the popularity of the Kindle Fire tablets.

Joanna Lambert, VP for global consumer product and engineering at Paypal said in a statement that by focusing on just two apps, the company will be able to “innovate and make enhancements to Paypal’s mobile experiences to give our customers the best possible ways to manage and move their money.”
