No real trial, cannot edit files in Files app, slow startup – Ulysses Mobile Review

Seems like a nice app, but just for some reference, there is no real free trial - you have to agree to a subscription and then have either 3 or 14 days to remember to cancel if you don't like it. Also, the app is extremely slow to start up. I have a brand new iPad Pro that I literally just purchased yesterday and the app took about 30 seconds to get to the UI. There is a black screen with a yellow ball during this time. Not sure what's going on, but this is a lot of friction. Lastly, it does not seem to integrate with the Files app, so I was not able to edit files I have stored there. I guess maybe that's not the purpose of this app, but just FYI that's the deal.
