Chris,
Are you using Sky Go Ver. 5.0.3.14???
As this version has a lot of bug fixes in it and its my understand the HUDL2 is ok now
I've just found out that Tesco no longer has any HUDL Tab stock and have scraped the HUDL altogether and no there will not be a HUDL 3
How much longer supported apps will continue I've got no idea but I can't see it for to long IMHO.
