Telegram has allowed its users to export chats from other messengers, for example, from WhatsApp, Line or KakaoTalk. This is reported in the messenger update notification in the App Store.
After updating the Telegram app, users will also have new features such as deleting groups they have created for all members, secret chats from the chat list and call history. It will be possible to adjust the volume of voice messages for individual participants, and also to complain about channels posing as official groups of famous people or organizations.
Back on January 8, WhatsApp added a clause to the user agreement, according to which the personal data of the messenger users will be transferred to Facebook. But due to massive user dissatisfaction, the changes were postponed until May 2021.
