Missing all presets

Yesterday I noticed my presets are gone. It's no longer available in the tool bar at the bottom of my iPhone screen. Today my presents are still gone. I still have photos but where did my "presets" go?? That's the only reason I have Lightroom. Now I just have a bunch of purchased presets sitting around and unable to use. Please help. I'd really like it back in the tool bar when working on a photo.  Photo attached shows where the present option usually is. I've tried everything. Resetting it turning phone on and off etc
