The subscription does not run by the custom user
I have created the alert subscription which finds the logged-in user's group and gets the list of users from the same group, in order to send email to all of them.
The subscription is working fine in development i.e. with the admin user.
When I log in using custom user and triggers the alert, the subscription is not getting run by the user.
I have provided permission to all the necessary entities for the particular user.
Can anyone help why the subscription does not get run by the custom user?
