@flying2holiday same thing happened to me yesterday. The processing tracking went and went back to identity details received. Rang the advice line and she couldn’t give me an answer as to why that happened. My application has supposedly been with the examiner for nearly 2 weeks can’t understand why. Coming up to my 10 week point of waiting now. So stressed as my holiday is next week!! Got a email response from the upgrade team Monday asking not to contact them again and that they have noted I need my passport for 26th June.
