There seems to be a change in how bots can message users on Telegram we used to be able to pass the chat id.

Now when we do this we get the error message

Any idea how our bot can now message our users that initiate a conversation with us?

method in question is

client.api.send_message(chat_id: <CHAT_ID>, text: 'Hi')

Could you provide the code of your bot?

This is a confirmed Telegram API bug, unrelated to the ruby gem. I have a dialogue open with them on Telegram support channel on Telegram.

Thanks for following up.
