Unfortunately Whatsapp is ending support of BB10 phones, as well as Koodo for the self-serve app. Inf act Koodo should have already ended support for it. I believe that Whatsapp has recently announced an extension on BB10 end-of-life, but it's ending regardless. I myself have a Z30 and will be moving on soon. If you want to keep a BB10 phone, you will have to accept eventual loss of compatibility with more and more apps.
