Good Day

We want to send scheduled reports to multiple E-Mail addresses. This seemed to work fine in the past. However, when I type in two addresses with the format "email1@mail.com, email2@mail.com" I get the Error "Invalid value specified for the parameter "to"." It would be great if you could fix this with the next update. Or do I have to use another format? Currently we are on 11.1 Build 11110.
