I’m not sure how many people still use Tumblr, but from the number of readers who contacted us about this, it seems quite a few Windows Phone users still use or want to use the service.
The app appears to have been delisted from the Windows Store, not showing up in searches, and if one try to install it from direct links we get the error above.
Reader Sabri Yurga asked Tumblr support about the issue and received the following reply.
There are of course multiple 3rd party Tumblr apps which we assume are much better than the dated 2013 version of the official app.
Ouga is one such as, which even supports Continuum for Windows Phone, and can be found at the link below.
