PLS HELP: Photos from Lightroom Mobile GONE

I opened lightroom on my Android phone today and was prompted with a message about storage, I was supposed to choose one but both options won't work when i click either one of them so I had to close lightroom and when I re-opened, all photos and folders have been wiped out.

Please help me. 

Im using Samsung note 9 and the free lightroom app.

Thanks in advance.
