T-Mobile REVVL 7 5G

Hello! I recently got a Revvl 7 5g and had the data transferred over. What was in Google photos is now on the revvl. There is no longer an icon for Gallery and I can't seem to access them. Today, I took a picture and it is not in Google photos, but when I went to post a photo on Facebook, gallery came up with the photos that should have transferred, as well as the photo I took today that I can't seem to access. Can anybody help? Thanks!
