This is very necessary, because if the owner of the group is no longer active, then the group will be abandoned. Therefore, there should be an option for group admins to be able to claim group ownership.
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
