Airplay overrides the chrome cast option on apps that use both chrome cast and airplay.
Apple needs to find a way to offer option to turn off Airplay especially since it’s a faulty and inconsistent app. I wish it worked smoothly but I’ve wasted hours with trying to get it to work. Until then, please enable an On/Off option. I read apple support answer to similar question but the answer was incorrect. Support said ‘to use chrome cast’ use apps that support that. I/others have … Vimeo and YouTube both offer chrome cast, but if trying to use on iPad, airplay overrides the option.
