First off, thanks so much for creating this, it’s great to have the functionality available again.
I tested with a flight from TQPF to KMIA: TQPF/11 DCT PJM B520 STT RTE6 SJU DCT ACONY Y308 MADIZ VIICE2 KMIA/26L
When I imported the route in the Longitude, it properly selected the VIICE2 arrival but did not select the MADIZ transition (or any transition) and I needed to go in and select it manually.
Not a huge deal but I’m glad I checked.
