Apple has finally approved an updated version of the Telegram iOS app, after the secure messaging company’s chief executive complained yesterday that the iPhone maker was blocking updates worldwide due to a Telegram ban in Russia, reports Reuters.

The Russian government first ordered a ban on Telegram back in mid-April, citing Telegram’s refusal in an ongoing court battle to hand over encryption keys that would allow the country’s Federal Security Service (FSB) access to sensitive user data. The ban has proved troublesome for Telegram, as it’s led to the blocking of millions of IPs on Amazon and Google’s cloud platforms and requests from the Russia government that American companies, like Apple, pull the software from their respective app stores.
