When you are inside the mobile app, the Channels/apps under both the Home Screen (Recent Channels section) and under the Remote tab (Channels section), are organized in the same manner as they are organized on the connected Roku device Home Screen.
If you want to display them in a different order on your mobile app, you will need to move them on the Roku device Home Screen to your preferred layout. (highlight the channel, press * button on your remote, and select Move Channel). You can do the above by either using the physical Roku remote or using the Remote feature of the mobile app.
If you go to the Devices Tab, you should see the options for Remote, Channels, and Media. If you select the Channels icon, you should see here a mirror image of your Roku device Home Screen layout.
After you finish configuring your Home Screen Channel/app layout to your preferred ordered method, the mobile app should now reflect this. You may have to restart the app or "forget this device" under the Devices tab and then just reconnect to see the app reflect your changes.
