dispatcher.OnNewMessage() doesn't work with old groups but works with chats. If I try to use dispatcher.OnNewChannelMessage() it works for both channels and groups

I have another bot replying to messages (github.com/go-telegram-bot-api/telegram-bot-api) and have already attached to some old group. I tried to use its token, the same - old bot is working, echo_bot is not.

Bot details:

• Groups are currently enabled for bot
• Privacy mode (https://core.telegram.org/bots/features#privacy-mode) is disabled for bot

APP_ID and APP_HASH was created yesterday

Group details - test one was created 24 Oct, another - earlier.
New groups I created today is okay
