This reply was in response to bwt615’s point (“maybe adding a way to control the ordering and sections”) – I’m aware that managing recommendations doesn’t address removing the recommendations for good.
Still not sure what app you don’t want to update beyond version 1.7.4 – if this is a version of Plex Media Server, it’s rather ancient (version 1.7.4 was released in June 2017 and you probably shouldn’t run that anymore).
