New requests no longer visible in Portal

[Evaldas]

OK, I've found this page  with some explanation, why my new Requests are not visible in Portal (and Customers don't get any notifications even if they are Reporters) - they don't have Request type for this Issue type.

HOWEVER, what I don't understand - why my previous identical requests (without Request type as well) WERE visible in the Portal and notifications were sent to the Customers.

See a previous "bug" Issue type and nothing as Request type assigned (same people participating) - viewable in Portal:

And the new "bug" with same story no longer visible in Portal (notifications not working either):

Hi @Evaldas issues without a request type (because they were created by agents directly via the Create button in JSM) were/are never visible for the Reporter on the customer portal unless they have a JSM license as well.

Your answer suggested me an idea - how were the previous requests created that they "worked"?.. I tried repeating and it worked - they all were created as a "Support" issue type with something as Request type, but then moved/changed to "Bug" issue type with nothing as Request type - and these work (in Portal and notifications as well)!

Perhaps it's a bug, but a good one for us :)
