Public calendar isn’t displaying anymore

Hello,

Thanks for your plugin. It was working great until yesterday. I use this plugin only for public calendars.

First time
I used this setting : [pgc public=”true” calendarsids=”[email protected]”] on my page and I also put the calendar ids on the settings page. Everything was working fine.

Second time
I used the exact same settings, but I decided to change the google account. I was not using the administrator account so I decided to change the API key from my personal account to the API key of the administrator account. Calendar has the same ids because it’s a shared. With these settings, the front end calendar shows “Not found. The specified resource was not found.”

I don’t understand because I have a public calendar on my google account. Nothing works anymore so I wondering what’s the problem.

Thanks for your help. I tried everything.
