Model class robovise.models.RoboProcessedFiles doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS Celery

I am using celery in my django project. 2 issues, the autodiscover task doesn't discover my task under robovise/tasks.py so I had to explicitly pass the path of the tasks file in the include argument of Celery instance. Then when I try calling the task in my django shell I get this error in Celery:

[2021-08-17 16:26:36,312: ERROR/MainProcess] Task robovise.tasks.process_new_users_resp[5763be00-77d4-4705-bb9a-6e06f2b03464] raised unexpected: RuntimeError("Model class robovise.models.RoboProcessedFiles doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.")

I've seen many post talking about this issue but have not found any solution. It's really strange as I have the same setup in another project and it works fine.

celery.py

from __future__ import absolute_import
from celery import Celery

# Set the default Django settings module for the 'celery' program.
# os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'financial_services.settings')

app = Celery('financial_services', include=['robovise.tasks'])

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

and here is robovise/tasks.py:

from celery import shared_task

@shared_task
def process_new_users_resp():
    from robovise.models import RegisteredUser

    print("IN TASK!!!")
    RegisteredUser.fetch_and_update_resp()

    return True

Also my settings.base.py:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'robovise',
]

/robovise/apps.py

from django.apps import AppConfig


class RoboviseConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'robovise'

/robovise/models.py

from django.db import models
from .services import (
    upload_req, read_res, read_primeid,
    read_positions, read_costbasis, read_acct_value,
    read_non_trade_trn, read_trade_trn
)
from django.db import transaction
from .tasks import process_new_users_resp


class RoboProcessedFiles(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    file_type = models.CharField(max_length=50, blank=False, null=False)
    file_name = models.CharField(max_length=255, blank=False, null=False)

    @classmethod
    def processed_file(cls, file_type):
        return RoboProcessedFiles.objects \
            .filter(file_type=file_type) \
            .order_by('-created_at').first()
    ...

Starting celery using:

 celery -A financial_services worker --pool=gevent --concurrency=500 --loglevel=INFO

and then the python shell where I call a function that calls my task:

 python manage.py shell -i ipython --settings=financial_services.settings
