Thanks for the update. It seems to have fixed whatever was going on. I went back in and removed the compatibility checkbox, tested - worked fine. With it in, it also works fine. COUATL stays up on landing in both scenarios. Personally, for me, leaving the checkbox unchecked seems to be a bit smoother for whatever reason, so I left it unchecked but either way, thank you!! Nice job. GSX back in business for me beautifully.
