dispatcher.add_handler(ChatMemberHandler(welcomeFilter, ChatMemberHandler.CHAT_MEMBER), group=WELCOME_GROUP)


There is no response anyone join the group or left the group why?(Member is hide)

Ptb version - 13.5

Because the group parameter of the handler is not what you think about… It’s the priority of the update to be received, if the update matches the filter of two handlers with the same group, the first one will be issued. You can change the group of the handler so your update can be handled by multiple handlers.

Have you added chat_member on the allowed_updates?

Where to add that?

Why are you using ptb version 13.5? Latest version is 20.5. Even latest non-asyncio version is 13.15

Ohh sorry printing mistake I am using 13.15 By the way If I update 13.5 to 20.5 it's getting many error

Here to add? updater.start_polling(allowed_updates=Update.ALL_TYPES, timeout=15, read_latency=4, drop_pending_updates=True) telethn.run_until_disconnected()

Sure

Already added

Yes - as described in the docs: https://docs.python-telegram-bot.org/en/v13.15/telegram.ext.updater.html?highlight=allowed_updates

What do you need "WELCOME_GROUP" for?

Стикер

I HAVE REMOVED THAT NOW

Yeah, ikr. Was asking again just to make sure.

No need to scream

You should ask in the ptb group ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
