Unable to programmatically view entire calendar from ics subscribe link

[Sum Juann]

I'm using the iCalendar python module to read in the .ics link you get from subscribing to a Team Calendar. The vevent data I get from parsing the .ics data appears to be from random dates, or at least only a couple months worth. When I import the .ics it into a calendar app like apple calendar or google cal, I can see all dates just fine.

import requests
from icalendar import Calendar

r = requests.get("url_to_cal.ics")
cal = Calendar.from_ical(r.content)

for event in cal.walk("vevent"):
  print(event)
