An error message is shown after plotting a route with segment “ADK G8 SYA”; it says that waypoint SYA is not on route G8 even though it is. This can be confirmed with the West Aleutian Islands FAA chart: https://aeronav.faa.gov/visual/10-07-2021/PDFs/Western_Aleutian_Islands.pdf
The red route line stops drawing at the international date line, so I am assuming the issue is related to that
