Unable to Complete Online Check-In with VF5Q5A on Turkish Airlines

I’m unable to complete the online check-in using my VF5Q5A reservation code. After looking at other complaints, I see many people facing the same issue. It seems like an overbooking tactic, and it’s quite disappointing. Turkish Airlines, this is not the standard one would expect, especially from an airline that claims to be Europe’s best. This issue needs immediate attention and resolution.
