Steps to reproduce:
MacBook Pro Retina 13-inch, 2015 Intel, MacOS 12.2 Beta (21D5025f) <--note beta OS
I downloaded the Orion browser from the link in the email sent by Vlad.
I double-clicked on the dmg file and opened Orion from Launchpad.
I followed the instructions in Orion Recommendations to import from Safari.
I also repeated these steps on a second MacBook Pro 13-inch M1, 2020, MacOS 12.1.
I expected Orion to show the same websites I designated for Autoplay in Safari > Preferences > Websites tab.
On the Intel Mac, a long list of websites showed up under Autoplay, many of which did not look familiar, and this does not match the Safari autoplay sites.
On the M1 Mac, Orion shows no websites under Autoplay, which also does not match the Safari autoplay sites.
(Five screenshots added below: Orion and Safari autoplay for Intel and M1; also Safari site settings for example site Dailymotion)
Orion, OS version; hardware type:
Intel Mac: Version 0.99.110-beta (WebKit 613.1.12)
M1 Mac: Version 0.99.110-beta (WebKit 613.1.12)
