Xbox App Not Showing all Screenshots

Hello. My Xbox App on my Samsung Galaxy is not showing all my screenshots that I would like to share on social media. It shows them all up until a couple of months ago but then it just shows captured clips, but no screenshots. I can see them from my xbox,
but not on the app. I can share them from my xbox to my feed, but still can't access them from the app.

I have reinstalled the app a few times and signed out and back in but nothing works. Is there any way to access older screenshots? Thanks.

:)
