Hi Clarence,
The Appeon Workspace in Google Play store might be delayed with updates for
some reasons and therefore is not recommended. You may install the Appeon
Workspace from the Appeon PowerServer (AEM Login page) so to make sure they are
compatible.
You can find the information below in PowerServer online help.

Task 3: Install Appeon Workspace (on the Android or iOS device)
Instructions for Android:
Step 1: Enable the Unknown resources option (in Settings > Security) on the
Android device so you can install apps that are not downloaded from Google
Play.
Step 2: Make sure your Android device can connect to PowerServer.
Step 3: Visit the Appeon Workspace download center that is posted on
PowerServer (http://Server_IP:80/AWS), and then click the download button.
Regards,
ZhaoKai
