The same for me. Two days ago my issues were listed. Now everything empty.
When I filter for issues created by "Winfried" those issues are listed which I created, but also issues from others.
When I filter for issues with "condition" in the title, the correct issues are listed.
Don't worry, your tickets are all still there. You can find them through the advanced search:
However, when you then visit https://tracker.adobe.com/#/view/FRMAKER-9134 it will show nothing.
In our internal ticketing system, all tickets are still there. We will look into that and check. I guess a security update of our internal system broke the external-facing front end (the "Tracker").
At least recently / today this has been fixed...
Thanks for confirming, Klaus. This has been fixed today.
