I have joined a certain telegram channel with two different telegram accounts. I run the below code to start both sessions using pyrogram and print the received message. But I noticed that when a message was received on the telegram channel only one of them printed and the other didn’t. However when I tested using my own test telegram channel I couldn’t repro the issue, i.e., both the sessions printed the message on the test channel. I’m at a loss why the problem happens with the other channel. Both the numbers are subscribed to the channel. What would possibly cause this behavior?

    message_handler('uk_number', message)

    if message.sender_chat is not None and message.sender_chat.id == CHANNEL_ID and message.text is not None:
        print(datetime.now().strftime('%d-%m-%Y-%H:%M:%S-%f') + ': ' + session_name + ' received channel message: ' + message.text, flush = True

    app = Client("india_number", api_id=config.getEnv("api_id"), api_hash=config.getEnv("api_hash"))
    app_uk = Client("uk_number", api_id=config.getEnv("api_id"), api_hash=config.getEnv("api_hash"))
    app.add_handler(MessageHandler(india_number_handler))
    app_uk.add_handler(MessageHandler(uk_number_handler))    
    await app.start()
    await app_uk.start()
