I suppose this is because the Android 4.0 and 4.4 are already very old but if facebook lite, original twitter and original facebook can be used without any problem why not twitter?
It should be noted that in Latin American countries these android are still used and many were disappointed with this new application, being lite was expected to save us more memory and that it would not be as heavy as normal twitter, but we came across this wall .
You could say that today android 5.0 is a low range and perhaps that's why the previous ones are not taken into account but the question is: Android 4.0 and 4.4 will be without many other applications while they are updating?
