I am having the exact same issues. USA user here. Changing browsers doesn't seem to help.

The issue seems to be around the week view - if you edit the interface to open in month or day view it works not ideal but a temporary work around i hope

Same here (UE). The problem happen when two or more events share the same hour and day and the page load in week view. Easily reproductible on a new base if you create two event at the same time and reload the interface page.

I am having the same issue.  Can someone from Airtable review and provide guidance? 

Same issue. 

Reached out to Airtable support and they have replied so just keeping everyone updated

Apologies for the inconvenience, and thank you for bringing this to our attention. I understand how crucial the calendar views are for your scheduling and planning purposes.

Our internal team is currently working on a fix for the issue affecting the calendar views in your "Scheduling" interface. We’re aware that other users are encountering the same problem with calendar views in interfaces, so it's something we're actively investigating. We appreciate your patience while we work to resolve this as quickly as possible.

Fixed. Just got an email from Airtable Support and I can confirm my interface works now. Thanks Airtable for addressing this.
