I can see them, I can delete them but I can't figure out how to edit them. For instance, I have a reminder for "Payday" every two weeks -- but the start date was apparently wrong. I can edit it on my phone but I see no way to edit them in Chrome, even if I'm signed in.
You can view & edit your Google reminders on https://calendar.google.com.
In Google Inbox app: https://inbox.google.com/reminders?pli=1
You can click on the reminders tab on the left hand side.
