SubPage Listpart on Mobile Client, limited to showing 5 lines then "More Lines Available" (NAV 2017)

jeffuk

We have a listpart as a subpage, you only get 5 lines on the screen and then it shows below it "More lines available", and the user must then click 'show as list' to get to the rest this isn't ideal as you can't easily refer to information on the parent page whilst populating the list.

Is 5 rows a hard, fixed limit, or is there some way to remove this limit, or at least extend it?

I've checked the instance settings, and the web.config files for the webclient, but can't see anything obvious that sets this limit, and none of the properties on either the parent or subpage seem to be related.
