Cannot find flights

After the most recent update, this app goes not work. Anytime you attempt to "book a flight" and fill in the criteria, it shows "we are not able to find any seats that meet your criteria." Ive tried troubleshooting with cities and departure dates. Nothing. Before this update, it was agonizingly slow too. Likewise, I have some one-time club passes I want to add and that isnt an option. Im disappointed with United. Hurry it up and fix it before you lose a regular valuable United card member!
