I will lovable flutterflow policies supabase rls fix supabase auth errors

Some users get permission denied, others see empty lists with no error, and nobody knows why. Usually that is RLS quietly returning zero rows.

Insider detail: a missing WITH CHECK clause lets users edit rows they should never touch, and a wrong email confirmation redirect URL breaks sign-ups. I check both.

What you get:

• Root cause found and explained simply
• Fixed policies for select, insert, update and delete
• Tests with real user accounts to prove it works
• Auth fixes: email confirmation, sessions, redirects
• Storage bucket rules (Premium)

Before ordering, tell me: the error message, which tables are affected, and whether I can get collaborator access to your Supabase project.
