There is no update now. I solved because I download the previous version 16 (.apk) searching online. Then I have installed manually. Now it works.
I have the same problem after the update of the app. I have an Asus Zenfone ZE551ML (ASUS_Z00AD) with android 5.0. is it possible to reinstall the previus version of apk? this is the version 21.0.0...
