No photos from iCloud showing up on new iPhone 15 Pro Max and I feel like I’m going insane.

I’ve tried almost everything. I originally wanted to download all the photos off my iCloud because I have increased storage now. So I turned off iCloud Photos, signed out of my iCloud account. This was to force the phone to download the photos in the cloud.

When I log back in, every photo in the cloud is no longer showing in the photos app. I went to iCloud.com to see if they even exist, and they do indeed exist.

I’ve tried everything to have to reload onto the phone: Reset network settings, switched back to optimize phone storage, restarted my phone. I have great internet connection and I have my phone plugged in as well. I’m 80% battery mode as well. Apple Support couldn’t help either. Pretty disappointing.
