@BarryCarlyon I’m actually getting two different cursors though the second page is in fact empty so I’m not sure about the missing channels 
Cursor One (same as yours just split to show the difference):
aW5zdGFsbCM 1NDQzMjg5 Mjp1ZGRmcGpwbTgzYmNqMzN2bXhreXpmN201NW8yMHE6
Cursor Two:
aW5zdGFsbCM 5OTgxNzY1 Mjp1ZGRmcGpwbTgzYmNqMzN2bXhreXpmN201NW8yMHE6
