Just about the most stupid idea MS or Skype have come up with, kill off an app months before the replacement and call the nightmare for all tablet users an upgrade......
Anyway for now just head for the store and install Skype translator, it's almost identical to the Metro app (With all the same faults) and just ignore the fact it can do translations.
Hopefully later on this year, maybe next or when the competition have buried Skype for good, MS will put out the updated people/phone/messaging apps that in theory will allow you to skype call or message right from there without using a "Skype" app at all.
However for the life of me I cannot understand how a company who goes to all the trouble to make a "Single" OS so universal apps can work across phone/tablet/desktop or Xbox cannot take the perfectly working Phone or Xbox One app and turn it into a universal app so people can have choice and something that actually works.
But what do I know I am just a customer..............
