Yes I am aware, thx for reminding. I just did not find a full opt out from automated updates - maybe just picking a date in far future…
Yet: I do as well like the possibility to stay up2date but am frustrated that I had two times issues with 2 releases this is 100% of all updates fail for me 
I no left the HA-Cluster enabled, looks as well all 4 nodes are being scheduled not as when I first tried HA and one node was set aside for spare.
Will see what happens with 1.20.3 update - is that any way to subscribe to release notifications?
Thx
Jens
