Hey guys I have a problem with my login. Is like I can use my credential of email and password to login into the main outsystems.com but I can't use the same email and password as my login details for my app preview. Did anyone else experienced that and what do you think I might be doing wrong or should do?

Hi Phineas,

This is because the OutSystems site and your personal Environment use another User Provider then your app.
If you go to <your Enviroment>.outsystemscloud.com/Users you will see all your users that have access to your apps. 

You can change your credentials there if you want to :)

Kind Regards,

Martijn Habraken
