Apologies for bumping the thread, but I'm in a similar situation. I've been able to view my reservation with the e-ticket number on the Turkish app previously, but now I'm getting "a technical error has occurred" when trying to view it for my flight in 2 days. I booked with life miles, and I heard that there was issues with Turkish in the past not getting paid by LM and therefore TK canceled the ticket. Is this something I have to worry about, or is this likely just TK IT living up to expectations?

Is there a workaround to view it without calling in or visiting a Turkish airport desk/ ticket office?
