I’m having exactly the same problem as this guy here, but clearing my browser’s cache and cookies didn’t solve it. My Gmail, Hangouts and pretty much everything else is working.
Steps to reproduce:
- Open Brave.
- Go to calendar.google.com, or go to mail.google.com and click on the calendar icon inside the overflow grid at the upper right corner.
I tried everything in the related post, but I can’t solve my issue nor reopen it.
The site is working fine in Chrome.
I’m using Ubuntu 18.04.
