Read magazines in your iPad Kindle app

For the longest time it has been an oddity that you could read Kindle subscription magazines on Kindle devices and on Android devices, but not on iPad!
I honestly suspected something "political" behind it, like related to Apple's commission policies re content bought inside an iOS app. But maybe not, because along with other interesting developments, this whole thing seems now to be fixed in the 2.9 version of the Kindle iPad app, it's a big update.
