Yesterday night, I opened the feedback app, but it kicked me out. When I reopened it, I had to sign back in, but it got stuck on a continuous loading screen. I tried swiping it from the background and reopening it multiple times, but it kept loading indefinitely. I waited for 1 minute, then 3 minutes, but it never stopped. This morning, I checked again to see if my reports had been opened, but the app was still loading.
Feedback app Broken!
It works for me, so FB is not broken.
