Hi Marco,
I sent you an email regarding the Recommendation Viewer topic, but I will also respond here as this information may be useful for the rest of the community.
Creo stability recommendations are still generated, albeit we have a significant backlog of issues to analyze, which is causing some delay. Our team is planning to expand our processing tool and we should expect some progress in this area in the foreseeable future. I know this is a topic that has been raised in he past already, but we have never been so close to a solution. The reason why you have not received any new recommendation may be caused by this backlog, or maybe because the exits that you experience are not yet handled by our recommendations engine. I am aware that you are in touch with one of our Support engineer about such issues and I advise we discuss these through this channel.
As I mentioned in my email, the eSupport recommendation tracker that you reference below will be retired as it has been replaced by a new experience. Be aware that at this time, while this new tracker add a bunch of new functionalities, the recommendations from Performance Advisor (Creo or Windchill) are not yet supported, hence you will need to view them directly in Performance Advisor. eNews & Alerts for these recommendations is still functioning, though.
I hope this brings some clarity.
Regarding the issue you face with the case list, we are currently looking into it and will contact you when we have an explanation.
