Thanks for the reply.
This is an almost empty install (Qlik AM training environment with just a few demo apps imported and some streams).
I just edited a Connection (changed the owner and pointed it to a different directory).
I started the reload task of the Ops Monitor. Waited a minute (though it was done in a second or 2).
I checked the QMC Change Log sheet and it only mentioned changed rules (of way earlier today); nothing about connections. The other sheets are almost empty.
Do you have an indication where in the Ops Monitor I should see that? Maybe I am overlooking something obvious.
