I have several PDF Portfolios I've made with Acrobat Pro DC and use them to quickly and easily reference product guides and literature when I'm on-the-go. The latest app update has killed this. I troubleshooted it to determine it is the app and not the iOS (tried this on several iOS devices running 14.2. One had the most recent app and it was broken, the other had a previous version and it worked. When I updated the outdated one to the current app build, the same issue occurred where when you go to open the file, nothing happens. This is extremely problematic and I have no way of downgrading/reverting the app so I am screwed. Please please please address this bug and fix it!
