Platform and Device: IdeaPad Flex 5, Windows 10, 16.0 GB RAM
I have used SeeMusic for about a month and a half; this issue has never been resolved previously. I also tried rendering using my phone, and the issue persists.

Thank you for reporting this issue.
It should be fixed in the Version 5.0.1 update.
The update should be available for Windows within the next hour, and on the App Store in the next 48 hours.
