Hi @teylyn1 ,
'make.powerapps.com' is quiet different from 'create.powerapps.com'!
'make.powerapps.com' is the web portal of PowerApps, the site offers you a variety of options for creating your own apps, opening apps that you or others have created, and performing related tasks. These tasks range from the most simple, such as identifying the license or sharing the apps, to more advanced capabilities, such as managing CDS entity, creating custom connections to specific data sources and deploying solutions.
However, 'create.powerapps.com' is a studio for creating canvas apps( Model-driven apps by App Designer, they are different ). All application design is in here, in the middle of studio, is a blank canvas, so you add any components, custom any function to create an app to fit the needs of users in your organization.
Generally, if we are going to edit apps, we first login to PowerApps Web Portal, choose the environment(important), managing the CDS and Connection if need, and then choose Create to naviagte to App studio to make an app.
Best regards,
Sik
