Missing Lightroom Library Photos

Hello Lightroom for mobile Community,

I went canoeing over the week and had it tipped over. My phone is now somewhere deep within the river. 😞

I now have a new iPhone with an old backup to use as a way to recover as much as I can. I was feeling upbeat about pictures being backed up on Lightroom for mobile, but after downloading the app it isn't showing any recent photos. The majority of the photos that were uploaded to this app are gone.

Can anyone help?
