Hey Jason, good to hear from you!
We're working on a daily basis with Freefly and Auterion to make final adjustments to the Astro's firmware to offer complete support in Site Scan Flight. It may not be quite ready for full support in the next app update in July, but it should be in the following version later in Q3.
If you want to beta test though, please send me an email, the processed results I've seen from the Astro are fantastic.
Regards,
Nico
