Here's another bug:
I installed the app, used it, didn't really like it, and uninstalled it. Now, everytime I turn the phone on I get 'resuming' message and it takes a second or two to show my previous lockscreen. Once it even resumed with the default factory reset lockscreen. I restarted the phone (soft reset) with the same result.
It's a little annoying; I hope after an eventual factory reset it'll clear up.
FOLLOW-UP: Reinstalling the app stops the 'resuming' message. Hopefully they'll clean up the uninstall process in a new version.
SOLUTION: I found the solution in this thread:
