I hadn’t used Katalon Studio since about version 7.0.1… I just downloaded the new version and it appears most of the functionality is only available now in the paid version? Am I missing something? When did this change happen?
From your brief description, it sounds as though your original KSE has “timed out” and now you’re reverting to KS.
The “change” as you put it, came with version 7.0.
