The problem

Calling api.reminders.post() returns a 404 error

Environment

• pyiCloud release with the issue (pip show pyicloud): 1.0.0
• Last working pyiCloud release (if known):
• Service causing this issue: RemindersService
• Python version (python -V): Python 3.7.3
• Operating environment (project deps/Docker/Windows/etc.): Linux

Traceback/Error logs

<Response [404]>

Additional information

When I do the refresh method and look at the data retrieved from the endpoint /rd/startup I get:
{'Collections': [...],
'Reminders': [
...
'startDateIsAllDay': True,
'title': 'Where are my reminders?'},
{
...
'startDateIsAllDay': True,
'title': 'The creator of this list has upgraded these '
'reminders.'}]}

Same thing here - but an additional point with the current source and reminders:

Calling the api.reminders as is would result in:

pyicloud.exceptions.PyiCloudAPIResponseException: Authentication required for Account. (421)

Specifically, as identified in #330 , the 'dsid' parameter needs to be added when the reminders api call is made:

def refresh(self):
"""Refresh data."""
params_reminders = dict(self._params)
params_reminders.update(
{"clientVersion": "4.0",
"lang": "en-us",
"usertz": get_localzone_name(),
"dsid": self.session.service.data["dsInfo"]["dsid"] <---- This key/value
})

^-- Adding the 'dsid' key and associated object to the 'params_reminders.update' dictionary got around the auth error (in services/reminders.py)

So now that the reminders call is working, the returned value when calling 'api.reminders.lists' is as follows:
{'Somelistname': [{'title': 'The creator of this list has upgraded these reminders.', 'desc': 'Learn more here: https://support.apple.com/HT210220', 'due': None},.... for each individual list.
This follows what we knew when Apple updated Reminders a few years back. So more-or-less, the above patch to services/reminders.py is required to get the API call to function, but the returned data no longer works for anyone who was upgraded their Reminders app(s) in the last 2 years.

FWIW - calling api.reminders.collections does seem to return the appropriate list structure and accompanying GUID.
