App isnt working

Ive seen really good reviews about this app & how cool it is, it honestly isnt working for me. Ive tried to upload a picture & it loads but everything else to edit the picture wont show, like no filters, brightness, all that stuff. I thought it was my phone, so I deleted the app several times, quit running the app, turned off my phone, & downloaded the newer iPhone software version lol. So am I doing something wrong or is the app under construction?
