Unfortunately I had to take the old mobile versions down from the app store. I didn't want to, but the app stores are applying more and more legal requirements to anyone who publishes apps there, including free apps. It was becoming too much to handle, even just to maintain the old listings. My plan is to make the new app available as a PWA app that you can install on desktop and mobile. Still need to work out some details on that.
Several people have asked for a printable update to OPSE with the changes that are in the app. Mostly this is just around how Suit Domains are applied. I'd certainly like to do that, and I will probably put out a print update once the changes from this beta are stabilized and I like how Suit Domains are behaving.
