Thank you James for the quick and kind answer!
Yes, it IS WORKING, if the parameters of the RSS config are as following:
Blog pages shown max: 8 Entries
Newsfeeds show last max: 5 Entries
Show in Newsfeed: Short text
It did not NOT WORK for me if parameters are like following:
Blog pages shown max: 8 Entries
Newsfeeds show last max: 10 Entries
Show in Newsfeed: Full text
Are feeds usually driven by the theme or the core files?
I can not exclude that as a cause, but I would like to determine what is going on here and find a solution.
