Apple Calendar not syncing with Google Calendar

My Apple Calendar is no longer syncing with Google Calendar.

1) When I add/edit events on my iCalendar app on my iPhone these do not appear on the Google Calendar

2) When I do the same but logging into iCloud and accessing Calendar, same result; no change on Google Calendar

3) Changes ARE syncing on the Apple Calendars (icloud and iphone app)

4) Any and all events added/editted on Google Calendar are synching TO my iCalendar app on my iPhone

5) I've tried deleting that Apple Calendars, then adding them back (copying the URL, paste, etc). When I do, everyting appears in the Google Calendar.

6) But, again when I try to add or edit Apple Calendar events, they do not appear in Google Calendar

7) Lastly, when I try to delete or edit Apple Calendar events via my Google Calendar I am unable. "You do not have permission to edit this event." pops up.

I've been on Apple Support via Chat. Nothing worked. Told me to check with Google support (which there isn't any) and then call the Apple support number.

Called the Apple Support number. They couldn't figure it out.

She put me on hold to speak with her supervisor. Came back and said that since the iCloud Calendar and iCalendar on my iPhone ARE synching with each other, then there isn't anything more that they will do. "It's a problem on Googles end. Is there anything else that I can help you with?"

Has anyone else had this issue, and if so, what steps did you take to make you Google Calendar receive Apple Calendar info?
