Please fix issue

Ive had this app for a while. All was good until a week or so ago when I received a text for a promo. I added to my wallet and the app disappeared off my phone.. Ive tried to download multiple times but get a message along the lines of something not working, try back later. Very frustrating because I use this app frequently. Please fix...
