KFUK you rang 
Speedy,
Which Lenovo do you have please TAB S8-50F orTAB S8-50L?? Both are running KK4.4.2 or have you updated to L 5.0.1?
My Lenovo YT2 1050F and YT2 Pro 1080F both run and work with Sky Go and the your Tab IMHO will do the same. It also has the same SoC as my YT2 10.1, Intel Atom Z3745
In fact the only Lenovo we have a problem with at present is the Yoga Tab 3 10.1 and this Tab will not run any of the Sky apps but this is being worked on by the Sky Go team.
I hope this helps you out.
