I am from Sweden and I have used Viber for a long time, all over the world (not that I think that matters now, but it always worked on my phone).
But since today (April 1st 2014) I get the same ominous message stating "Disconnected. Messages and calls are unavailable"
Yet I can still update my contacts, update my profile and download new stickers... But I cannot talk to my friends, which at the moment is extremely important -and we would all hate to have to resort to Skype (or any other app for that matter).
I went in on Play Store and I saw there was an update, but no change for the connectivity after installing it.
I sometimes use my 3G connection, but mostly I use my home WiFi -which is what I am on right now, so there's no problems with connection at all (seeing as how ALL my other apps still work and connect).
Also, when trying to email a backup I am not allowed to choose ANY app that could successfully perform this task -no browsers at all, just other messaging apps like whatsapp, secure chat, bbm etc.
Not that I know why there's even a choice for backing up msg history if I can't restore it...? "Here you are, sir... This is the backup of everything you hold dear in this place -BUT YOU MAY NEVER BE ABLE TO VIEW OR ENJOY IT AGAIN!!! (except for -maybe- when you login to your email)"
So... What's the deal, will I (and all my friends) have to select another app, or is this a passing thing?
My friend in Switzerland confirms the same msg there... So I guess it's temporary
