Android version shows different content from web version

In the Android mobile version I see different models I created than in the web version.
Of course I logged in with the same account.
It looks like the mobile version is showing models I created some years ago, while the web version shows models I created more recently. Also I see some difference in my name.
This last difference looks like there are actually 2 different accounts in the background, while using the same login credentials.
The web version I open on I suppose this is the same platform as the Android App is using!? Or are these 2 different products?

How do you determine the model version?

  • date
  • preview image
  • actually opening the file?

Does it happen on another device where the app hasn’t been installed before (that means where there cannot be older cached previews or models saved on the device)?
