Adobe Lightroom mobile photos and presets deleted after update

Hello, My lightroom mobile got recently updated and it deleted all the photos and presets that I created. All those presets were saved under user presets. I had 11 GB of photos in lightroom mobile app, 35 user presets and 2 presets were saved from discover. I would really appreciate if I can receive any help on recovering those photos and presets. I pay for subscritption services as well. It's my months of hard work that just vanished. I work day and night in editing those photos. Would reapply appreciate the help here. Thanks
