application that i created. I tried with the documentations and I succeded
to get them, but i have authentication problems and couldn't view them.

Could anbody tell me in details how i must do it to upgrade it succesfully
point by point?

I don't really understand the thing with ownership. Could you explain it me,
please?

Thanks for help!
