Since OCP 4.15 we see issue with OLM deployed operator unable to operate in watched namespaces (multiple). It works fine with single watched namespace (subscription). Also, same test passes if we don't deploy operator using OLM, but using files.
It seems like it is permission issue based on operator log. Same test works fine on any other previous OCP 4.14 and older.
