After update to 11.0.2 RSS is not syncing

update was smooth but after enabling apps again my rss feeds do not update though cron job is running. I am missing something?

Log:

This could be a workaround or solution (or a hint for debugging): After adding a new feed to my feedlist everything is updating again, will check this later on.
