Seeing the same blank v0 preview pane issue tied to auth iframe/CSP behavior in sandbox.
A mitigation that helped: add a dedicated sandbox flag (V0_SANDBOX=true) in Development only, then bypass/stub auth only when that flag is on.
Keep Preview/Production unchanged with normal auth enabled.
In practice, this worked best when covering client imports + server imports + Edge middleware (sandbox no-op, non-sandbox real auth).
Not a universal fix, but it can isolate sandbox rendering issues without affecting normal environments.
