If you're having trouble with the app, try the following:
- Log out and log back in.
- Switch from mobile data to wifi.
- Visit the apps area of your device settings and clear the cache and data for Tumblr.
- Remove and reinstall the app, making sure you’re using Android OS 5.1 or higher. You can get the newest version at https://market.android.com/details?id=com.tumblr, but the Google Play store will offer you the latest version that can run on your phone’s particular OS.
- Check your phone storage. Is it full? If so, consider deleting all your non-Tumblr apps. 😉
