Not sure if this helps, but I managed a workaround.
I am on version 226, so I filtered the GetAppVersions to be greater than the date of the 200th version, this returned 26, I then added 200 to the result. This gave me the correct value of 226.
This would require updating each time the version surpasses a value divisible by 100, not perfect, but works.
CountRows(
Filter(
PowerAppsforMakers.GetAppVersions(
LookUp(
PowerAppsforMakers.GetApps().value,
properties.displayName = "App Name",
name
)
).value,
properties.appVersion > [date of last version divisible by 100]
)
)+ [number of last version divisible by 100]
