Hi BDFCI,
Thank you for reaching out Microsoft Community. We're sorry for the inconvenience this has caused you.
Since the issue only happens on a specific application, then the point of failure lies within that application itself. Knowing that you already contacted the MiM support and was told that others didn't get this kind of problem while using the Surface Pen, have you asked what is the version of this specific application on others' devices? This is for us to know whether the issue is due to the updates rolled out by the software developer.
You may need to contact MiM support again to check the version of the app on others devices so we can further determine how we can go about fixing this problem.
Kind Regards,
Crest
