Plex update broke ChromeCast - Something went wrong

Constantly having this problem, it’s super annoying since I use plex heavily and my entire house has Chromecasts in it. Getting really tired of rebooting my phone, the chromecast and the plex server to resolve this.

Casting works fine when I cast from a ChromeOS device on the WebUI. But using the phone almost always results in a “Sorry! Something went wrong”.

Sometimes rebooting the phone fixes it, sometimes rebooting the Plex server fixes it. I really hope someone from the Plex crew looks into this.

Issue presents itself on a Pixel 4 XL and a Razer Phone 2 so I doubt it’s a Android OS version / phone issue.

I should note this latest issue was not resolved by rebooting the phone and I just wanted to get to watching my movie instead of screwing around with troubleshooting plex yet again and did it from my ChomeOS tablet.
