get_chats() does not work as expected.

Hello, I noticed this behavior more that once.

I have a group that sends ~1000 messages per day, where in each message there is an image, so it takes a while to synchronize.

The original code was:

tg.login()

result_get_chats = tg.get_chats()
result_get_chats.wait()
if result_get_chats.error:
    print(f'get chats error: {result_get_chats.error_info}')

def new_message_handler(update):
    ....

tg.add_message_handler(new_message_handler)
tg.idle()
tg.stop()

And with this code, when I launch a bot (after e.g. 2 days that I wasn't use it), it fails to synchronize the messages in a short time interval and then it behaves like that messages are received in real time.

I added also a time.sleep(30) before def new_message_handler(update) but it does not improve.

How to be sure that get_chats() works as expected and fetches everything before start to work? Basically result_get_chats.wait() should do the job but it doesn't.

To reproduce, I think you need to setup a bot, make a login, then shutdown and fill a group with thousand of messages/photos and then start again the bot.

Hi,

I suspect that you’ll need to use getChatHistory (reference) to properly load all messages.

I see that the current limit for get_chats() is 100.

Do you think that overwrite the limit could help?
