Issue getting Photos to Appear on App but Show on Web for Lightroom

I just bought a Pixel 10 and got it all set up on Monday. I opened the Lightroom App for the first time today (it was downloaded when my phone was set up using sync), and none of my photos from Lightroom are appearing. They do show on the web version of Lightroom.

Is there anything I can do to get my photos back on the app?
