Apple has removed Telegram's official app from its App Store, owing to the claim that telegram had made inappropriate content available to its users.
The move came shortly after Telegram launched an unfinished version of its "experimental" Telegram X app. Apple took down both the official messaging app and the one still being developed.
Prominent reporter of technology site TechCrunch, Natasha Lomas speculated that the new app could have fallen foul of Apple's rules requiring all apps to have filtering and blocking systems as well as ways for offensive content to be removed hurriedly.
Telegram's founder Pavel Durov tweeted "Once we have protections in place we expect the apps to be back on the App Store."
Telegram has been condemned by some governments for using end-to-end encryption that protects communication between users.
Certain law enforcement agencies have complained this data-scrambling technique could make it hard to investigate some complex cases.
But earlier this week, a former independent commentator of terrorism legislation for the UK government, David Anderson, called the technology a "desirable fact of life".
It did make some aspects of an investigation more complex, but this was offset by the huge amount of information available from other generally less well protected sources, he added.
