If you don't mind losing your settings in MobileSheetsPro, you could try resetting the settings to the default under Settings->Other Settings. Alternatively, you could just go to C:\Users\<your username>\AppData\Local\Packages\41730Zubersoft.MobileSheets_ys1c8ct2g6ypr\LocalState, rename default.xml to default_backup.xml, and then restart MobileSheets. That would let you test out the default settings without losing your current settings. I just want to know if the hovering works correctly with the default settings, in which case we can explore what settings are conflicting.

In the OS Pen & Windows Ink settings, did you enable anything like "Let me use my pen as a mouse in some desktop apps"? There aren't really any other settings I'm seeing that could be involved.
