It would be great I had had a group, once I have to deactivate my account, so i grant some users with admin permission, and when I created the new account, they made me admin too. So if there is a way to reclaim ownership of my old group, I definitely will be thankful to Telegram.
Problem illustrated. We are mere admins and the owner lost his account info.
I totally agree. this function should be implemented as soon as possible as has been happening for some time on whatsapp
