All good things must come to an end.
I like Google Hangouts
No ad-ware on my Samsung smartphone using Hangouts, What'sApp, Viber and IM+ Pro!
PS.: The following is somewhat of a rant:
Aside from having lost my interest in Messenger Plus! a long time ago, I'm also losing my interest in Skype due to it being taken over by Microsoft, and since then poorly (or not at all) updated. Even the "Messenger" integration in Skype is a disaster.
It looks to me that all they've done is set the Messenger servers to only accept log in from official Skype client, which in turn simply logs in both Messenger and Skype once your accounts are "linked."
On top of that, the "linking" works poorly. Logging in with Microsoft account will load both Messenger and Skype contacts, logging in with Skype account will only load Skype contacts.
This makes it significantly harder for Mobile messenger apps to support Messenger in Skype. IM+ Pro was one of the first third party apps with support for logging in with your Microsoft account, however they do not have access to load your Messenger contacts regardless.
