The provisioning assistant in Program Portal doesn't allow me to add dot for App ID(like com.company.app). I can only add App ID with com.company.appname in Program Portal without assistant. But that App ID doesn't show up in assistant, what's the problem?
The provisioning assistant tries to be overly helpful if you're used to doing the task by hand. In other words, you're expecting to enter "com.company.appname", but the assistant doesn't want that. Instead, the assistant wants what it calls "AppID Description", with no periods ".", and the AppID will be generated from that.
Yes, it's confusing. If you want "com.company.myappname", then you want to enter "myappname" when prompted for AppID Description, and the real AppID ("com.company.myappname") will be generated from that.
Frankly, I haven't found the provisioning assistant to be any more helpful than doing it the other way, and as you've found it's a bit confusing.
My only guess as to why your other AppIDs don't show in the assistant is that they use wildcards. All of my non-wildcard IDs show, but none of the wildcards do.
