voyagerspacecraft I was referring to the earlier versions of GraphenoOS that have been released recently (I assumed that releases starting from 2026061800 are Android 17). I was able to open the app since then, and also able to cast to my TV.
The final A16 release was 2026061600. There were announcements for other releases (2026061800, 2026062100, 2026062200), but I believe those releases didn't make it past the beta channel at the furthest. I believe 2026062300 was the first A17 to reach stable.
If I have that right, if the device was subscribed to experimental, alpha, or beta, it might have run 2026061800, 2026062100, or 2026062200. Otherwise, like most devices, it probably jumped from 2026061600 to 2026062300, in which case the observed change with this app would be exactly a change from A16 to A17.
Is the behavioral change due to a transition from 2026061600 to 2026062300 (most likely) or from, say, 2026062200 to 2026062300?
