Photos disappeared suddenly from my phone

Hi ,

yesterday I got new Iphone 16 pro, i had an iphone 11 before so I transferred the all the data along with the photos to the new phone and all went well.

i woke up this morning i had 7000 photos and after a while it became 2000 photos, I don’t know where the photos have gone!! Even though i tried all the tools and ways you mentioned on your website to recover them, I found 1000 photos in the recent deleted but the rest have been gone !!

can you please help on this case please .
