detransport_lviv_telegram's Issues

Is this bot instance running in webhook mode?

I have seen your code running in polling mode, but the delay time is very low. And my bot runs in the same way, with very high delay time.

My bot: https://t.me/policr_bot

By sending the /ping command, my bot responds for about 3 seconds, and yours is less than 1 second.

Why is this, do you have a clue? We simply call the send_message method, using the same library. Unable to understand ☹.
