Woocommerce -> mark pending orders automatically as processing

Hi!

I’m having problems with my WooCommerce website. As soon as someone pays via a certain payment method the status is set to “pending” instead of “processing”. This means my customer doesn’t get any emails until I manually set the status to “processing”.

Is it possible to get “pending” orders automatically marked as “processing”? Which code I could use to do this?

Any help is appreciated!
