I am not sure if this is the correct place to ask this question, so please move this question if not in the right category.
I had the plex working great with my chromecast until last night , now I can’t cast anything, it is showing me a screen on my tv, that says something like "One more step, please complete the security check … " and it asks me to check a box on my tv, without any ability to do so.
I’ve attached a screen shot, the chromecast is working fine with other services like youtube or just a tab casting from the chrome. but for plex i get the same issue when trying to cast from my phone or from my browser.
Please let me know if you have any solution for me.
I don’t get the same options as you do , but I still have the same issue with my plex application on my android device.
there I can’t be mistaken it should cast without any issues, while still I get the same error page.
