I started to convert a lot of my content in AV1 until I realized that my Nvidia Shield devices won't play AV1. My $30 firestick will play them but I do really prefer the Shield. I guess I'll wait it out and hope for a new Shield (it's been 2019 since Nvidia released one) but i'm not going to hold my breath.

Put VLC on them. See if it works for your AV1 videos.
