Personally I stick to the plan of ignoring it. The environment works, therefore i feel like there's nothing to be done on my end.

For the record:

I have set up the environment (2 UAG, 2 CS) in 2306 in the first place, so nothing that is 'fixed' by updating to that version. And since those message appear and disappear all by themselves ... ¯\_(ツ)_/¯
