User can't delete documents created by himself

Hi guys, I trying to use cloud as back-end for small reactjs-app but facing with several issues:

1 - When we changed auth provider from the keycloak to auth0 user can't delete document created by himself anymore, they can create and update but delete always cause an The current user is not authorized to perform the requested action error

2 - I gussed it can be related to changed identity and tried to delete the user and re-acreate him again with the same email. But when I try to create user via admin panel I see an user email duplicate error. Also the User (role: guests) missing scope (account) error appear if user tried to login via oauth2 on the front-end.
