San Francisco, Oct 26 (TIWN) Apple-Meta war over App Store has intensified with new updates that require iOS developers to give Apple 30 per cent cut on the sales of 'boosts' for posts in a social media app.

The move will affect Facebook and Instagram which let people pay to boost the reach of their posts, reports The Verge.

It is also the first time that Apple has directly taxed advertising in iOS apps.

"Apple continues to evolve its policies to grow their own business while undercutting others in the digital economy," a Meta spokesperson was quoted as saying in the report late on Tuesday.

Apple previously said it didn't take a share of developer advertising revenue, and "now apparently changed its mind".

"We remain committed to offering small businesses simple ways to run ads and grow their businesses on our apps," said Meta.

Paying to boost posts is a common feature across Meta's family of apps, all well as Twitter and Chinese short-form video platform TikTok.

In a statement shared with The Verge, an Apple spokesperson said the App Store has long taken a cut of digital goods and services.
