@bot.chat_member_handler doesn't work sometimes.

1. What version of pyTelegramBotAPI are you using?
   pip3 show pyTelegramBotApi: Version: 4.8.0

2. What OS are you using?
   MacOS

3. What version of python are you using?
   python --version: Python 3.9.7

As the title says, @bot.chat_member_handler doesn't call the function sometimes. But it seems like after updating bot token it starts working as intended.

The code is:

@bot.chat_member_handler()
def chat_member_handler(status):
  print(status)

UPDATE: I already have allowed_updates set to telebot.util.update_types

chat_member update type is not in the default set of handled update types. Set it obviously when call palling/creating webhook

@Badiboy Oh, I forgot to mention that I already have infinite polling set like this:

bot.infinity_polling(allowed_updates=telebot.util.update_types)

[cc00010]

and in webhook as well:

bot.set_webhook(url=webhook_url, drop_pending_updates=True, \
    allowed_updates=telebot.util.update_types)

[Badiboy]

If set - means that Telegram does not send them. Check bot settings (privacy etc.) and group settings (bot is admin, bot have enough permissions).

[cc00010]

Could you please tell me that particual setting? There are many of them.

But the weird thing here is that if I revoke the token, the issue is gone.
