I am an educator and have a student using Lightroom Mobile v5.2.1 on an LG Stylo 5 and using v9 of Android. When the student takes a picture using the LR mobile camera, the little preview appears at the bottom left but after returning to "All Photos", that picture can not be found. The student has tried sorting by capture date and has checked that there are no filters turned on. The student has also cleared the cache. Any additional advice would be appreciated.
