If you want to install Tumblr app on your iOS device you won’t be able to find it on App Store because it is missing from it.
According to Tumblr, it is “working to resolve an issue with the iOS app”. But it is still not confirmed that whats the reason behind it missing from the store because it was removed by Apple, or by Tumblr itself.
Certain iOS users reported earlier this week there were problems with searching in the iOS app Safe Mode wasn’t on.
As Reported by PiunikaWeb, Some users who deleted the app in an effort to reinstall it found out that it was now not available on App Store, but according to some iOS users, you still can re-install the app by going to their purchases page.
In the past, many apps were removed by Apple so it is not a new thing. At the start of this year, they removed Telegram after they found out that the messaging app was being used for illegal activities such as distributing child pornography.
It is clearly mentioned in the Apple Guidelines any app found on App Store must have some sort of content filter to get itself out of controversial material, and Tumblr is an open website where you can find any type of stuff. So it might be the reason that Apple removed Tumblr from App Store.
