All you should need to do is log into the app store with the email address you used to purchase MobileSheets/MobileSheetsPro and it should let you download the update. Contact me at mike@zubersoft.com and we can investigate this further. Please provide the email address you used to purchase the app through the Google Play Store in the email you send. I can't look up purchase information for the Microsoft Store version, so if we can't figure that one out, you may need to contact Microsoft directly. The one thing I'll say is that you need to make sure you use the Microsoft Store app and not a web browser. Similarly, you should use the Google Play Store app on your Android device instead of a web browser.
