Hi @alano444 ,
Could you please share a bit more about your scenario?
Do you mean the created canvas app could not show up within your PowerApps Mobile App in Android device?
Further, does this created app show up within your PowerApps web portal (https://make.powerapps.com) in your New Environment?
If the canvas app is shown up within your PowerApps web portal (https://make.powerapps.com) in your New Environment, the same app would also be shown up within your PowerApps Mobile App in Android device.
Please check if the version of PowerApps Mobile App in your Android device is the latest version, if not, please consider upgrade it to the latest version, then check if the issue is solved.
Also please consider uninstall the PowerApps Mobile App from your Android device, and then re-install it again, check if the issue still exists.
Best regards,
