Apk install does not show top bar feedback of installation results anymore

Since SFOSX 3.4. (Xperia 10) I do not get any visual feedback while installing apk apps via file manager. Albeit the apps gets installed. In SFOSX 3.3. I always got informed via a top bar with the result of the installation process (succesfull installed etc.). This is a clear regression between SFOSX 3.3 and 3.4.

Does some one have a working feedback action on SFOX 3.4 - to approve the opposite?
