App not working – SSI Mobile Wage Reporting Review

I’ve had this app for a long time, I’m trying to report my income since yesterday and the app won’t work. I have an iPhone 11, no pending updates on this phone. What could it be? I deleted it and reinstalled it again and same. Funny thing is I installed it on my daughters iPhone 7plus and it worked. Please help!
