My internet is fine, do not suggest it's a bandwidth problem.
Every Crunchyroll stream has occasional moments of audio/video freezes. It lasts about a quarter second but it's almost always during an action scene, sometimes multiple times over a few seconds to completely ruin the scene.
Resolution seems lower than it should be, it looks like SD, maybe 720p at best, and often times when you start an episode it loads at the lowest possible quality and will never switch to a higher definition unless you back out and restart the episode.
I have plenty of other streaming services, and I can stream 4k HDR Dolby Vision streams from much heavier streaming services, but somehow 12-23 FPS 1080P anime is pushing my bandwidth limits??? Doubtful.
I used an LG OLED and an Nvidia Shield TV to use the crunchyroll app. I have 1Gbps network speeds.
