Prior to eVisa and we had one page sticker for the non O visa in passport.
Then to do extensions (extension of permission of stay not visa) you included photocopy of the page with the non O (expired)
Even when you renew your pp the information about the non O is transferred to new pp.
Thinking your thread a reminder to does with an eVisa regardless of what type, you need to hold onto a copy.
Easy mistake to have overlooked that..
