There was an old issue with the @oiTubeBot
Now the issue is resolved by prompting Gemini to fix, and Gemini fixed the issue within three minutes

@oiTubeBot is the only YouTuBe downloading bot in Telegram without any channel subscriptions or ads in private messages. This is the only bot in Telegram which you can use without requiring to start a private chat with the bot 😎 and hence ആഗ്രഹമുണ്ടെങ്കിൽ പോലും എനിക്ക് ads send ചെയാൻ കഴിയില്ല😌
