needs more stability

I like the idea a lot, but …
… the first PDF I chose was displayed all black although the tile rendered correctly
… whenever I click on a tile with a web link, the app crashes
… exporting a board to iCloud Drive and importing the pbz in the iOS app did not work
I want to use this app, but right now that is not possible.
