Recording didn't capture audio? Make sure the SampleShot broadcast is selected in the screen-recording sheet, and that the source app is actually playing. Some DRM-protected apps block capture.
Mic track missing? The microphone must be armed in the system broadcast sheet as well as in SampleShot's settings.
Sync not moving items? Both devices need the same folder chosen in iCloud Drive (the Mac uses iCloud Drive › SampleShot Sync automatically) and iCloud Drive enabled. Give iCloud a few minutes to upload between devices.
Restore purchases? Settings → SampleShot Pro → Restore Purchases.
