Fix it

Not a bug. A stale session.

The processes explain the trip. This explains the moments ORUS itself gets in the way — a button that should be there and isn’t, a certificate that won’t update. Every fix here is cited to something BIR actually published, not a forum guess, because the honest answer to “is this a known issue” deserves a source.

Not a bug. Your ORUS session is holding the registration record from the moment you logged in, not the one BIR just updated. Synchronize and re-login pull the current one.

Practical guidance, not legal or tax advice. ORUS behaviour changes between releases; each fix links the source it’s cited to so you can check it still holds.
