Cannot leave a review for CL using iPad!

Just wasted an hour attempting  to leave reviews for CL's that we have recently stayed at.  Also problems in general accessing most things on CC website with iPad 

it appears that iPads are not CC compatible.  Shame, as when we are away we are more likely to have the iPad rather than a laptop.  

Come on CC - it's not rocket science and iPads have been around for a while,  when will you get your act together?
