A Black Box pops up on the screen and refuses to let me shop - or even enter Sephora! It tells me that I "MUST" install the New App ... I've tried for about 3-4 weeks. Major Fail! The app goes 'round & 'round forever (never stops even after 1 hour). This horrid app simply will not install - period! Stress 😬 and anxiety ... Please help! This is my 3rd attempt at asking for help 🆘 I've been dealing with Sephora for about 30 plus years ... really getting tired of this.
