A quick Google search pointed me to this thread on reddit
Following a link posted in the comments, and then going to the "android" tab (which I totally missed at first) I found these instructions
- Open the Google Calendar app.
- Tap the session.
- In the top right, tap More.
- Tap Delete > This session or All following sessions (and stop scheduling).
- Tap OK.
I'm just wondering where I would find "This session" or "All following sessions", because I don't see it:
I'm using Calendar Version 5.5.15-129963483-release and I thought I might be out of date but there doesn't appear to be a newer version on the Play Store.
