Android app: duplicate messages when moved to another folder

It seems that other users are also having similar problems:

Number of Mails in Inbox is different as in Windows Client

I’m using the iOS App on my Smartphone and the Windows Client in my Notebook. The Number of Mails in my Inbox is different on my Windows em Client as in the App. The App is showing Mails which I alsmost deleted or moved to another subfolder. When a Mail comes in, I will process the mail, then I move it in a subfolder (Windows Client). When I go in the app, I can still see the Mail in the main Inbox folder

Sync of deleted messages

When I delete email in the desktop app they disappear from the server but the mobile app (Android) still shows them and I have to delete them manually all over again. Any advice?
