I would recommend to make this post sticky as many users seem clueless.

The Play Store page clearly indicated the web site address, which not many seemed to have read. That page is:

http://android.moneymanagerex.org/

Please *read* the information on this page. It is put there for a reason. It will list all the sources of relevant information.
There you can see how to download previous releases, where the announcements are posted, where to ask for help, etc.
Reading it will help YOU, the users, get to the appropriate information.

Also note that, if you don't have time to answer others' support questions in the forum then probably others also don't have time to answer yours.
