If you would like to try installing the FastSpring version of MobileSheets, we can try and see if it performs any better on your device. That version is given access to a permission that is not normally allowed through the Microsoft Store - the app is not allowed to be suspended by the OS to recover resources. This ensures the app won't be closed while multi-tasking even if the system is low on memory. I don't know if this is related to what you are seeing in any way, but it's something we can at least try. Contact me at mike@zubersoft.com if you want to give this a try.
