still (!) must use v10.5.0 on iOS 10.3.3
This WAS a nice little utility program that I would use a few times every week for planning my schedule, but these updates killed it for me. This probably has to do with the fact that I'm still using iOS10, but now every time I try to run it, it immediately loses focus, and refuses to come to the foreground. Luckily, I managed to get the old version back, but most people wouldn't have a way to do this.
Response from developer
We have updated the latest SDK. Please check it again. Thank you!
