Plot hole: At the end of Spectre Blofeld loses his eye in the crash. In No Time To Die he is being held in Belmarsh Prison, which is high security and holds many terrorists like him, but despite all the high security somehow he has access to a bionic eye which was given to him while in prison. This would've been thoroughly checked many times before being classed as safe and given to him.
Continuity mistake: James Bond was wearing a black tie when he visited Vespa Lynd's grave. This was still evident when he knocked Cyclops off his motorbike in the following action sequence. During the fight as he grapples with Cyclops, not only is the tie missing but the top few buttons of his shirt become undone.
