Notification overload with 78% of employees feeling overwhelmed by notifications
Mobile app performance issues including lag and slow syncing
Huddles limited to 50 people and cannot be recorded

End-to-end encryption applies only to Secret Chats; private and group Cloud Chats use server-client encryption, so Telegram holds the data
Secret Chats are device-specific and are not part of the Telegram cloud, so they can only be read on the device they started on
Logging out destroys all of your Secret Chats
The Secret Chat self-destruct timer applies only to messages sent after the timer is set and has no effect on earlier messages
Telegram states screenshot detection cannot be guaranteed on some Android and Windows Phone devices, so screenshots of Secret Chats can be taken silently
Messages cannot be forwarded out of Secret Chats
The self-destruct timer in cloud chats covers media only, not text
