I am pretty sure everytime you uploaded a new page of your passport, you were overwriting the previously uploaded page. You should cut and paste each photo into a word document and then convert it into a PDF, then upload that 1 PDF.
Anonymous participant - Nope, it says as it appears in your travel document. Your Passport is your travel document, not your driver’s license. A foreign government would never take your driver’s license as a “travel document”.
Cambodia has always been 11 business days. Not clear what time you submitted, but possible yours took 12 business days (or the standard 11). This has been their normal processing time for all visas since Oct 1st.
Anonymous participant - Actually it states to answer as it appears in your travel document. Whatever you entered will need to correspond to your travel document (e.g: passport). If it doesn’t, they will usually cancel your application and you fortify the fee (for some reason they are very strict with this).
