Unfortunately they ignore a lot of stuff, like shows in the grid guide being 3-4 hours off if you scroll around it in Android. It makes the grid guide useless in that app, very basic and easy to replicate for anyone that would care.
I have given them a lot of credit for fixing issues that have been raised here by me and many others, but some of the easily replicated, common stuff like this that's seen by many doesn't even get acknowledged as worth a fix.
