Hi Dimitrij,
thanks for answering.
This option was always on, because I want to be warned when I‘m in timeshift before switching channels. That works as expected.
Whats new is the fact, that it warns when I want to shutdown. In that case I really don‘t care weather I‘m in timeshift or not, because I want to stop watching.
Shutting down only used to be only interrupted, when there are active recordings. But then it shuts down automatically later, when the recording finishes.
Timeshift does not, because it never ends automatically.
