We can't turn on the requestor notification on "New ticket created", because it will always send the English notification instead of those for other languages.

The problem appears to be that the language recognition for new contacts takes too long to run in the background, and as a result. The notification (in the wrong language, English) is sent first, at which time the contact's language is set to English. A few minutes later, I can observe that the contact's language is changed to the proper language. However, the wrong notification has by then already been sent out.

This would appear to be something that could be fixed fairly easily, by having the notfication sendout delayed until the language recognition finishes. 

I would appreciate it if you could look into this, because for some customers, a confirmation of receipt is very important.
