The difficulty is in reproducing the issue. I've tried letting the tablet sleep and opening the app every 20 minutes, but it's been responsive for me every time. So I can't determine if this is a problem in MobileSheets itself, something with Windows or display drivers (due to the use of the Win2D library which utilizes DirectX) or something else altogether. I'm also using a Surface Pro 4, so I don't know if the same issues will occur as on the Surface Pro 7 or the Surface Book 3. It would also help to know how many users are seeing this issue, because I still don't know how prevalent it is.
One major difference with MobileSheets vs other apps is that MobileSheets is a UWP application so it has to deal with the lifecycle stuff which is only applied to UWP apps. Microsoft is pushing hard to allow older Win32 apps to have access to modern frameworks, and this seems to be their focus vs improving UWP. So what I may wind up doing is converting MobileSheets to be a regular desktop/Win32 app so that I don't have to deal with all of the limitations of UWP. I don't know if it would fix this issue or not, but it could help depending on what is causing it.
I'll keep working to try and reproduce this issue, but if you have any recommendations for things I should try, please let me know. If you want to provide me with your library through a backup file, or at the very least an exported setlist, so that I can test with setlists that are known to have issues for you, I will give that a try.
