The dish is for Astra 28.2E definitely, though there may be an Astra 19.2E
that I'm not aware of.

Should be no problem then.

"Unconnected". I have a question though, what exactly do I need to do to fix
the LNB status? Do you mean the 2nd method that I listed in my original
post, i.e:

Capture card -> DiSEqC in the configuration of the capture card ->
"(Unconnected)" -> switch -> switch Type - DiSEqC, number of port 2 -> ESC
-> "(Unconnected)" -> LNB from the list (switch, rotor, LNB) -> "Universal

The dish is not accessible to me since I live in a shared flat, so I cannot
do anything wrt LNB on the dish itself.

Thanks for the input
best regards,
