Bug description

Since I updated ejabberd from from version 23.10 to version 24.02, noticed that the option welcome_message: of the module mod_register no longer works as expected. Newly registered users do not receive the welcome message anymore.
No changes have been made during this time to the configuration file, so that's why I am not sharing it here. After updating to version 24.06, the problem persists.

Please, can someone using this feature, confirm that it works so I know if it makes sense to continue looking for the cause on my side?

Thank you!
