Regarding updation of bot username
I had an bot with previous username @Learning_point_bot. By using telegram support I changed its username to @LibraryPoint_Bot. But Telegramic Bot is confused among usernames. Even there is no option to edit username. Please look into the matter.
Hi,
We updated the username of that bot. Thanks for letting us know.
The owner of that bot can now edit the bot and get its new name and profile photo from Telegram by updating it.
