How do I unhide photos on my iPhone running iOS 13.3?

Open your Photos app

Select Albums at the bottom

Scroll down till you find Other Albums and select Hidden

Select the photos you want to unhide (Tap on Select at top right and choose the photos)

Tap on the Share icon located at bottom left

Scroll down and select Unhide.

Hope that helps.

One more time, once you open the photos app, Tap on Albums (at the bottom) The screen that opens up needs to be scrolled down until you find a section marked Other Albums and the Hidden option is underneath it.

You are welcome and I am assuming that you are all set and your concerns are addressed.
