Why isn't my list updating every loop for this discord bot

The goal of my bot is to grab info from another site and send a message. For whatever reason my bot is able to send a message at the right time everyday but the message is not getting updated.

@bot.event
async def on_ready():
    print ('logged in')
    msg1.start()
        
@tasks.loop(hours=24)
async def msg1():
    activity = []
    update_info(activity)
    channel = bot.get_channel(channel_id)
    await channel.send('\n'.join(activity))
    print ('scheduled message sent')


@msg1.before_loop
async def before_msg1():
    for x in range(60*60*24):
        if dt.datetime.now().hour == 10: 
            print ('its time')
            return
        await asyncio.sleep(1)

bot.run(DISCORD_TOKEN)
