We are currently experiencing a system issue where the Tabbed UI attendee form is allowing registrations to proceed even when required fields are left unfilled. This may result in incomplete attendee data or registrations not being properly recorded in our system. Our engineering team is actively investigating the issue and working on a fix. We will share updates as soon as the issue is resolved. We strongly recommend using the Dynamic or Simple UI for all attendee registrations until this issue with the Tabbed UI is resolved. Thank you

We’ve identified an issue in the May ’25 Webapp release where registrations using the Tabbed UI could succeed without completing all required form fields. This resulted in errors during registration processing, as incomplete data cannot be processed in Salesforce. To prevent further impact on our users while our Engineering team works on this issue as our highest priority, we are rolling back the Webapp to the April ’25 release. This rollback will restore the proper required field validation behavior. We will share updates as soon as the issue is resolved. Thank you for your patience and understanding.

We've successfully rolled back the May ’25 Webapp release to resolve the issue with the Tabbed UI attendee form. Required field validation is now working correctly, and registrations are processing as expected. We’re continuing to monitor the system and investigate the root cause. A full post-mortem will be shared once the analysis is complete. Thank you for your patience and support.
