I suspect the developers of Whatsapp (like the developers of any successful, cross-platform app) rely quite a lot on help from Nokia, in testing on their various platforms.

Nokia management won't be particularly thrilled with Whatsapp helping out N9 users, given that it and the platform have been kicked into the dust.

However, I'm pretty sure that Jolla will be courting Whatsapp, so I strongly suspect that there'll be a native Meego version of Whatsapp when their device launches. Once that's available, it should be much easier to quickly repurpose for the N9 and be a great deal more reliable than Wazapp.

So to those who want something 'perfect', you probably will get it, just not yet.
