Hello JimbzyR - thank you for getting the app! Unfortunately, that would be very unfair to other owners of the app. The refund policies are covered by the policies of each store.
What I may suggest, if you notice anything buggy, please join us on Discord and share your issues. The last new version in Android (2.10.0) is quite an improvement in the usability of the app on Android, and I am doing the best I can to get the app to be awesome in all platforms.
Your feedback is appreciated, help me make it worth the buck and let me know what didn't work out :) Join the chat on Discord and happy to chat.
Best regards
JV
