We've seen an increase in "Failed to load call object bundle" errors within the past hour. This happens when the browser is unable to download our JavaScript bundle from the CDN. If this happens to you or your users, you should be able to refresh the page and join your call successfully. We're working with our CDN provider to identify the issue.
