Telegram Bot API Fix Needed

I'm in need of an experienced Python programmer who can solve a critical issue I'm dealing with, with my Telegram bot's API. Specifically, I've been facing an inability to send messages. I need someone who can solve this particular problem by implementing a different API library. Ideally, the freelancer for this job would have a solid understanding of the Telegram bot API, in addition to having experience with Python and API libraries implementation. I'm looking for a thorough, effective solution rather than a quick fix. Please bid if you can deliver this specific requirement.
