Rebuilding PapayaMobile after falling off Apple platform

Founder of Beijing-based PapayaMobile, Si Shen, has told the BBC how she had to rebuild her business after her mobile games disappeared from Apple's Appstore because of technical issues.

She lost investment and had to start afresh on the then-new Android platform, before rebuilding the infrastructure to sell on Apple's platform once again.

She says she has learned not to rely on just one platform - and that anything can be overcome with belief and persistence.
