CiviCRM 4.7.30, current Webform CiviCRM 7.x-4.19
When 'Send Confirmation Email' = Yes on the CiviEvent, filled out. When the user submits Webform CiviCRM, the event participant is registered successfully but no confirmation email is sent. I reverted the CiviCRM email template for Event Online Registration to default, to rule that out.
Workaround - we made the email send from Webform, but this is a bad workflow for staff who just wants to make CiviEvents.
Does anyone else have this issue?
