Live view stays on longer - what's changed?

Until very recently live view only remained active on my fire tablet for a few minutes at a time. But now, beginning a few days ago live view remains on all day, and only disconnects sometime during the night.Is this a [good] quirk of my setup (nothing's changed on my end) or is this an update to the Ring app?I've also noted that even prior to this latest change, live view remained on longer on my Fire tablet than on my Lenovo Android tablet set up right next to it. Is there any feature in the Fire tablet that would make Ring perform better in the Fire than in straight Android, or is this just a coincidence?
